Since the 1960's Maine Coons have become increasingly popular, throughout the United States and all over the world. Recognition of the breed was first given by the Canadian Cat Association and the American Cat Association in 1967. Other registries soon followed suit, except for CFA, which waited until 1976.

Some of the earliest Maine Coon Catteries include:

  • Abnaki - Liz Bicknell
  • Havenwood - Patricia McIntire
  • Heidi Ho - Connie Condit
  • Highmeadow and Kent - Diane Ziessow
  • Illya - George Andre
  • Jo Stad - Rod & Betty Ljostad
  • Le Beau Minu/Mountview - Carol & Tom Pedley
  • Mor-Ace - Anthony Morace
  • Norwynde - Lillias Vanderhoff
  • Quan Yin - Cynthia Wilson
  • Sundar - Phyllis Voth
  • Tanstaafl - Beth Hicks
  • Tati-Tan - Sonya Stanislow
  • War-Tell - Florence Wartell
  • Whittemore - Ethelyn Whittemore
  • Woods End/Woodriver - Diane Reynolds
  • Yankee Cats - Judith Ansell

Dauphin de France of Tati-TanThere are three catteries, perhaps more than any others, that created the foundation of most of today's Maine Coons. In particular, there are 5 foundation cats that seem to appear in pedigrees more often than any others. The Top Five, in order of frequency of occurrence, are:

  1. Andy Katt of Heidi-Ho
  2. Bridget Katt of Heidi-Ho
  3. Dauphin de France of Tati-Tan
  4. Tatiana of Tati-Tan
  5. Whittemore Smokie Joe

After these very prominent 5, it becomes more difficult to determine the frequency of other cats occurrence in pedigrees.

It is estimated by the breeders who created this site, that the genetic make-up of the average pedigree of the 90's, when traced back to foundation, contains:

65-70% of the top five cats
50-55% of the top three cats
35-40% of the top two cats
30-35% Clones

Leo, Maine Cat, 1884-1901

Please note that these figures are estimates of the average pedigree. These percentages will vary somewhat in different countries around the world. Most importantly, it is a "starting point", as a basis for comparing pedigrees. The high percentage of Andy, Bridget, and Dauphin is probably due to the popularity and widespread use of the "clones", kittens from the matings of Heidi-Ho Sonkey Bill with Tanstaafl Polly Adeline. A pedigree of the clones is available on the Maine Coon Database, listed on our links page. Ulrika Olsson first created the system for determining the genetic percentage of Foundation ancestors and Clones in Maine Coon pedigrees, and this system was later adapted for use with the CompuPed pedigree program by Astrid Straver. Most of the analyses on this site were generated using CompuPed 4.

Tanstaafl Polly Adeline of Heidi Ho

In 1978 Heidi Ho Sonkey Bill was born, a grand son and double great grand son of Andy and Bridget Katt of Heidi Ho. When bred to Tanstaafl Polly Adeline the amazing thing was that their offspring all looked alike, almost like clones... So when we nowadays speak of "clones" we are talking about the sons and daughters of Sonkey and Polly. The significance of the clones is, that they were used over and over, because they threw nice show quality cats and really added size. So many breeders decided that if a little was good, a lot was better. So although the clones themselves did not have a very high inbreeding coefficient (9.4%), there was done a lot of line breeding with them and their offspring. Nowadays many Maine Coons have pedigrees with 35% clones, sometimes even up to 50% clones. If you analyze pedigrees of today's Maine

Coons then there is this very *one* couple that is so prevalent in our pedigrees.

The pedigree analysis below indicates the genetic relationship of the clones to their foundation level ancestors.

It is not where we are today that is the main problem - most MCs are still healthy - it is the direction of our breeding that is the problem. If we continue this way we know from other breeds (cats and dogs) that problems will appear in the future. The use of clone and top five percentages is to get an idea about how valuable (from the gene-pool point of view) are the genes a cat is carrying. Breeding will never be an exact "science", you will never be able to calculate exactly what should be done. But you can use statistics/mathematics as a tool when deciding what to breed from and how to breed these selected cats. Mathematics should not be over estimated here. Calculations will NEVER eliminate the need of a breeder's judgement. But we must not UNDERestimate the help that we can get from genetic calculations either! They are valuable tools, when used correctly and in a sensible way.

The time has come to strengthen our gene pool through outcrossing, to maximize genetic variability in the cats we produce, to insure hybrid vigor, and to maintain a healthy gene pool for the long term survival of the Maine Coon breed. No one, and no one cat is going to be able to expand the size and diversity of our gene pool in just a couple of generations. It's a long-term project requiring the input and co-operation of a large majority of breeders, not the small minority. It takes a conscious effort and agreement within a breed to value health and actively breed toward that goal. It's how we choose and what we choose to breed that's important. Making that effort will definitely improve the health, vitality and vigor of our cats and kittens. The immune systems of all animals are absolutely dependant on genetic diversity.

Many new breeders are surprised to find, when researching a pedigree, that by the time they reach foundation everything has gone back to just two cats. This is a homogeneous cat, there is no diversity. There are a great many cats out there with very few names at the foundation level. Exchanging pedigree information is very important as we look for unrelated cats to strengthen our genetic pool through outcrossing. This is especially important for the new breeder who is supplied with 5-generation pedigree and, because all of the cattery names are different, assumes that this cat is not inbred. You need to know the "old lines" to see how they are so inter-related. With a good pedigree program, some patience and the will to research back to foundation, you'll learn how outcrossed or inbred the cats are that you are dealing with. The better educated and knowledgeable you are, the better chance you have of finding and making good, intelligent, logical breeding choices and decisions.

All About Maine Coons

You just can't imagine how many myths about Maine Coons I had to listen to during the entire existence of our cattery. Despite the fact that the Maine Coon came in Russia for more than 20 years, myths about these huge cats continue to exist to this day.

So it's time to refute them.

If you are interested in the Maine Coon, you have probably met information that there are American and European types in the Maine Coons.

What are they and how do they differ from each other? This division is primarily associated with the development of the breed.

Cats have a huge variety of colors. What color are Maine Coons? Many people believe that the colors of Maine Coons are limited to the classic black tabby, but it is difficult to imagine that Maine Coon colors and patterns has more than 50 variations.
