General Questions on Outcrossing and Foundation Breeding
........only three things are needed to do foundation breeding successfully: a vision, a plan and the cats to throw over the plan.......
Q: What is an F1 or F2?
An F1 is a first generation Maine Coon foundation cat. This cat can be found in the wild, on a farm or can be obtained from a private home or shelter. None or only one parent of an F1 is known and registered. An F2 is a second generation Maine Coon foundation cat where both parents are known and registered. An F3 is a third generation Maine Coon foundation cat where both parents and both grandparents are known and registered. An F4 is a fourth generation Maine Coon foundation cat - and so forth.
Q: What is the difference between foundation, part foundation and outcross?
Before looking for outcross it is important to understand the words foundation, part foundation and outcross. A foundation cat we call a cat from newer lines that are 100 % different from the ones in a common pedigree. A part foundation cat is a cat with a certain amount of foundation mixed with a pedigreed cat from common lines. Part foundations can vary a great deal in their foundation content. Most times cats in higher generations have less foundation content than cats in lower generations unless the foundation breeder manages to keep up high foundation numbers for several generations. Part foundation cats and even some full foundation cats can already have a pedigree with several generations. An outcrossed cat can be anything from foundation to part foundation to a cat with a regular pedigree. It all depends on what we are outcrossing to. So, the word outcross can be misleading as well. A cat can be a half-sibling to one cat and a total outcross to another. Some people consider a cat with a full pedigree, but a low Clone or Heidi Ho content a sufficient outcross to other pedigreed cats. For an explanation of the words Clones, Top Five, Top Three, Top Two and Heidi Ho please visit the Maine Coon Heritage Site http://bowen1.home.mindspring.com/mchs/home.htm on the internet). Others feel that every cat with a pedigree from show lines needs a part foundation cat to get efficient results regarding health.
Q: Are there several methods of foundation breeding?
Yes, there are different methods of outcross- or foundation breeding. There really is no set way of doing this. It all depends on the individual needs and goals of a certain breeder. One way is to use full pedigreed show cats and cross these out to foundation to give the line an immunity boost. The advantage of this procedure is that the show cat will give us quick results concerning type and size, at least for one generation. It is not hard to produce good looking Maine Coon cats if one parent is linebred and from show winning lines. This is very exciting. The breeder can continue the look that he/she loves and that is specific to his/her cattery without sacrificing much type. This method will definitely better the immunity in your kittens and reduce the risk of genetic problems. The disadvantage of this method is that the genetic value of the new line will be lost very quickly in case you are building up pedigrees and are selling kittens to breeders. For example if we cross a full pedigreed cat with an F1 100 % foundation cat, our F2 generation will automatically be 50 % foundation. Then if we cross each generation back to a full pedigreed cat, the foundation content will only be 3.13 % once we reach F6 when a cat is finally showable in CFA. Will this be enough outcross for other breeders? Most likely not. If the foundation breeder manages to introduce different foundation lines in each generation and crosses these again to "somewhat" different show lines each time, he can keep about 50 % foundation up to higher generations. It is not advisable to breed the foundation/show line mixes back into very similar or too closely related show lines.
Another method is crossing part foundation cats to part foundation cats. These are Maine Coon cats that are already outcrossed in themselves. Those cats already have a mixed pedigree with a little bit or a lot of foundation in it. Breeders then usually watch that each pedigree is relatively low in common lines and especially low in Clones since the Clones are the cats that worry us the most and where most of the inbreeding has taken place. The disadvantage of this method is that the looks in the offspring can vary a great deal and it can take a while until consistency in type and size is reached. The advantage here is that there will be a good amount of foundation content left once we reach 5th or 6th generation - more to work with for other breeders. More benefit for the breed in general. Another advantage is that a female with an outcrossed pedigree has a better chance to conceive and manage her role as a mother. This can give the line an easier start than starting out with an inbred female.
It is also possible to create new lines from foundation lines only. Very few of us are doing this at the present moment. The goal here is to have a 100 % foundation cat at F3 or F4 or even F5. A lot of cats are needed and it will be exciting to see how they will look like once they reach showable status. If we keep a positive attitude and work hard, the "barn cats of today" could very well be the show cats for tomorrow.
When deciding on the foundation content in the cat you are purchasing, ask yourself the question: How much fresh blood will be necessary for my breeding program to boost immunity in my kittens and/or hopefully get rid of problems that have manifested themselves for many years? Sadly, nobody can answer that for you. All we can do here is guess. Some breeders might not have experienced major health problems in their breeding program. They are simply looking for outcross to increase hybrid vigor in their kittens.
Q: I want to start outcrossing. How much foundation content do I need?
Fist of all you should be commended for taking a step into the right direction. In the beginning, it might be a good idea to run all your pedigrees through the Swedish Pedigree Database on the internet: <http://www.tdb.uu.se/cgi-bin/MCO> and find out about their Top Two, Three, Five and Clone content and make decisions accordingly. What is your goal? Do you want to provide others with outcross or do you simply freshen up your own lines? When looking at your pedigree, it is important to also consider foundation cats besides the five most common ones, in order to find a suitable outcross. They might vary to some extent in certain pedigrees. If you have mostly cats with full pedigrees and all from common show lines, where Clones are often skyrocket, it might be best to look for part foundations with a relatively high foundation content, since a pedigree with low Clones or Heidi Ho will probably not do the job for you. Then think about what generation you want to start with. Remember that cats in lower generations can only be shown in HHP class. It can take several generations until the offspring can be shown in Championship class. If that bothers you, you might be better off with an F4, F5 or F6. Also, check with your association in your particular country if they allow foundation cats in the breed and what the requirements are. If you are a new breeder, stay away from early generation cats and cats with a very high foundation content. We will get to this later.
Please remember that some sacrifices regarding show success are inevitable. There needs to be a willingness to settle for less for a while when it comes to outer appearance. Many foundation cats have the more modest, traditional look with shorter bodies, shorter muzzles and smaller ears. This will take some time to get used to.
Q: I have been breeding for a while and want to bring in some fresh blood. What do I do?
If you already are an established cattery and want to bring in some fresh blood, start with very carefully selecting the pedigreed breeding cats that you want to use with your new foundation cats. This is probably one of the most important steps for successful outcross breeding. Before going on a search for outcross, evaluate your own breeding stock in an objective manner. Kind of from the outside looking in. Try to chose the best and healthiest only - do this in a very critical manner. Don't try to fix up cats that already have many health problems. Females should be proven queens and mothers of several healthy litters without deformities, a low stillbirth rate and a reasonable litter size. There are still quite a few healthy Maine Coons out there, even with a 26 generation pedigree!! If you have a choice, try to use only cats with healthy gums and teeth and a good immune system. Also, watch for gentle and loving temperament and of course a good type and size. You will need good traits to balance out the weaknesses in your foundation cats.
If you have a big cattery, a foundation/part foundation male would probably be more economical and get you further ahead quicker than a female. Remember, you are on a journey and looking for outcross will be something you will need to do on a regular basis in the future, if you seriously want to help our breed. To find breeders who work with outcrossed lines, you can visit the heritage site, but be aware of the fact that not all catteries displayed on this site actually work with newer foundation lines. Contact breeders and ask for referrals. Most foundation breeders get along well and work with each other rather than against each other. You will find that there is a lot less competitiveness among foundation people than we find in the show world. They are also often easier going when it comes to working together and try to give each other grace to make things more enjoyable.
When it is time to buy new breeding stock from foundation breeders, be on the alert. We have heard horror stories about living conditions and breeding practices. There are just as many BYB among foundation breeders as there are among show breeders. Get many references and ask many questions. Visit the facility if you can. Make sure they test their breeding stock for breed-specific genetic problems. Also, they should take disease control and hygiene very seriously. Reputable foundation breeders will not sell breeding stock until they feel confident about their new line. Early generation cats will often only be traded with friends in order to try out the lines together. Sometimes early generations will be sold to breeders after the breeder had several healthy litters with a cat and feels relatively secure to release the offspring. So, there is the possibility to purchase an F2 or F3 after a few years of work with these new cats.
Q: If outcrossing is the best way to get rid of health problems, why test for Hypertrophic Cardiomyopathy (HCM), Poly Cystic Kidney Disease (PKD) and Hip Displasia (HD) ?
Just as much as testing without outcrossing is not sufficient, it is the same vice versa. Even though outcrossing is the most efficient way to breed away from genetic problems, testing for genetic diseases is still required. Nowadays, breeding Maine Coon cats without testing their hearts can be compared with driving a new car off the lot without checking the engine.
The chances for the foundation cat to have HCM are relatively slim, but possible. Also, there are other heart problems besides HCM that can be determined with the right equipment. Even though we have a good idea where heart problems in our pedigreed cats came from, there is a chance that a foundation cat could be diagnosed with HCM or some other heart disease as well. Fact is that we have enough heart problems in our breed already. So we want to carefully watch not to double up on weaknesses in certain organs.
When starting a foundation program, ALL cats we are using must be HCM tested, or we are seriously wasting our time. They need to be screened with Color Doppler Echocardiogram equipment by a specialist, preferably by a cardiologist - if available in your state or country. All breeding cats should be screened up to older age. Please follow the guidelines of the cardiologist in your country in regards to testing intervals.
Hips should be x-rayed by your vet for hip displasia and sent into Penn Hip or OFA if available in your country. Relatively reliable preliminary results can already be obtained for cats that are 10 or 12 months. This works well for foundation breeding. If you have high risk candidates in your pedigreed cats, it is possible to obtain OFA prelim results at a younger age. The inherited form of Poly Cystic Kidney Disease has also become more of a problem these days, due to its autosomal dominant inheritance. According to medical research, a PKD test at 16 months of age is apparently quite reliable. PKD testing is not expensive and can be done with the same equipment and at the same time as HCM. Many vets give a package deal on both. Breeding cats can also be tested for Patella Laxation, a joint problem in the knees of the cats.
The most reliable solution would be to keep early foundations for several years. However, this suggestion seems quite unrealistic when dealing with early generations. No matter how long an F1/F2 is being used, the foundation cat should also at least be screened once before it is released into a pet home, even if it is only a routine test. Remember that even though this is very unlikely, there is a slight chance in any foundation cat that it could be somewhat related to a cat from common lines, especially when obtained from a shelter where no information of ancestry can be obtained. Again, there is no set way of doing this. Each person has their own method on when and how many times foundation cats get tested. An option might be to place them into pet homes and get their hearts checked again at a later date. Even though your chances are lower that a foundation cat is affected by hip displasia, HD cases have been reported in full foundation cats as well. The perfect solution would to keep early foundation cats for many years and treat them like our show cats in regards to HCM, PKD, HD and PL.
The reason for outcrossing is to gain better health. When dealing with dominant genes like HCM or PKD, only one breeding partner has to have the gene for this disease in order to have a 50 % chance of our kittens to inherit this gene. Meaning that no matter how big the foundation content in a pedigree is, the *bad* gene could have worked it's way through right up the cat we dealing with at the present moment. Also, even though HCM can often be detected at young age, it sometimes does not show it's real face in an untested cat until age 7 or 8 - through a blood clot or kidney failure - both can be a side effect of HCM. This means that we often think our lines don't carry the genes for HCM simply because the offspring we have produced is too young reveal the problem. Cats grand and disappear, grand and disappear. Breeders secretly receive replacements - and these replacements also grand and disappear. When working with foundation, why taking risks and waste our time by using untested cats? One single breeding with an HCM or PKD positive breeding partner can destroy a new line that somebody has put so much time and effort into. Some precious lines can quickly be lost because the foundation cats were crossed to HCM positive Maine Coons, then spayed or neutered and the line was finished right then and there.
There is no point in outcrossing if we don't go all the way and use all medical science available to reduce the risks of genetic problems. Also, it is very likely that there are already many litters being produced these days where both parents are untested and actually have HCM. What is going to be left? Let's skip a show and do what needs to be done first.
Q: What can I expect health wise?
It took many years for our breed to get to a point of great concern. Problems will not go away overnight. Foundation breeding is not the answer to all health problems. Donna Chase from Thunderpaws has a favorite saying: "A new line will not perform a magic trick on our breeding program. That's why we call it "working with foundation." Yes, foundation cats can get sick too. They will, like all other species, carry undesirable recessive genes that might never show up until bred to a cat with the same problem. We are talking about genes that usually get lost in the process of outcrossing - but not always. Also, each breeding can bring us between one to four new gene mutations that would have not happened in any other breeding. No guarantees here folks!
Please note that the following things are very likely to happen but nobody can promise you that they will actually happen overnight - some things might not happen at all - some things might even get worse. Do not blame the foundation breeder if things don't work out the way you expected:
What we will most likely see is a positive effect on the cat as a whole. We will probably find our cats to become more intelligent and less irritable. Excessive shyness or aggressiveness in certain lines might disappear. We will probably see less problems in conception, birthing and kittening. We will most likely see less deformities, less stillbirths. A greater number of babies will survive common respiratory problems without or very little medical intervention. There will be fewer reactions to vaccinations. We will eventually get larger litters with not many runts. Weight and size of males and females will be more equal in our litters. We can have less diagnosis of early cancer, Felv/Fiv and Fip which are all mostly immune related problems (Fip lately being suggested to be genetic as well). Gums and teeth will eventually get better. Our goal is also to eventually get rid of heart, kidney and joint problems - a goal that can be reached as well if we outcross on a continuos basis, make no harmful compromises and test all breeding stock on a regular basis.
Q: I only sell to pet homes. Do I need to outcross?
Absolutely. Many people believe that only people who provide other breeders with outcross do something good for the breed. However, is it not the pet owners who will promote our breed the most? Is it not them who deserve a healthy companion with a good immune system? Pets have the same value as breeding cats and deserve to be outcrossed. Yes, people who only sell to pet homes will greatly benefit from broadening the gene pool in their breeding program.
Q: I am a beginner. Can I work with foundation?
Yes and no. It is very important to get to know the breed standard first and also to learn about genetics, health and colors of this breed before getting started - no matter if you want to become a foundation breeder or a main stream cat breeder. This can take several years. I personally believe that it can be more rewarding for a new breeder to start out with cats that have a nicely outcrossed pedigree. The art of breeding is mostly acquired through mentor ship and experience and it is probably easier for a newbie to worry about registering new lines and trying to breed out kinked tails or bad chins, than having to deal with deformed ribcages, no teeth in their cats' mouths at age two, intestines inside out and kittens dying of HCM at their new home. A lot of breeders have started out the common way, have landed flat on their faces and are now desperate for outcross. Supportive mentorship and a group of people to work with is the key to successful foundation breeding. However, it is probably more advisable for a new breeder to start with an F5 or F6 outcross, where much previous work with this particular line has already been done. Most times a pretty good standard type is already reached by this time which makes it easier to work with.
Q: What should I expect to pay for an outcross?
It is often believed that foundation cats should be lower in price than pedigreed cats. It needs to be mentioned here that when we buy a part foundation/foundation cat, the value of this cat is not based on titles, lynx tips or ear set, but rather on bloodlines and testing history of parents. The value is in the outcross in itself. Do not be surprised if you pay the same price or more for an outcross than you would pay for a show cat from winning lines. Foundation breeders often let their pets from early generations go for a greatly reduced price and need to get their money somewhere to be able to continue with their work. If we consider the present situation in our breed, a foundation cat has the same, if not a greater value to a breeding program than a show cat.
Q: I want foundation, but please with rabbit ears and alligator muzzle!
We often see people wanting to buy outcross but at the same time not willing to sacrifice type and size. On one hand we want foundation, on the other hand we really want this cat to be decent looking. Sadly, foundation cats do not conform in every way to the current standard and need to be worked with. They will probably not grow as big and long as some cats that are heavy in common show lines. As previously mentioned, the ears might not be as big, coats might be different in texture and length, coloring might be washed out, muzzles will most likely be shorter, chins might be weaker, sometimes we see rather cobby bodies in early generations, all depending on the line of course. Breeders need to understand that they will not get a perfect cat when looking for foundation. If they want a cat with a high foundation content, they are required to work in their own breeding program to achieve better looks. There will always be some effort involved. Foundation breeders cannot be expected to provide a finished product without fault or wrinkle. If you are suffering from "regional winner syndrome", foundation breeding won't be too much fun for you.
Q: Are We creating a separate Breed?
We breed with foundation to broaden the effective population of the existing Maine Coon breed. The intention is not to create a separate breed. All new foundation lines should be integrated into the general gene pool at one point in time. The reasons why some foundation breeders keep a *small* percentage of their foundation cats separate for a while are:
1. Many breeders who inquire about foundation lines have only cats from common pedigrees. These breeders often cannot register an F2 or F3 in their country. They need cats from higher generations. By the time a full foundation cat reaches fourth generation (F4), it's outcross value is still 100 % and most beneficial for their breeding program.
2. Developing new lines from scratch is a special challenge that some breeders find very rewarding.
3. Extra security . While some cats from a new line get integrated relatively quick, it is wise to keep a few cats of that same line separate for a while because of the HCM issue for example. *
