Non-CFA Recognized Large House Cats Breeds
The Chausie and Savannah are also notably large breeds. In fact, the Savannah cat is a veritable giant that can often reach a weight of 28 pounds. Unfortunately, due to their heritage, none of these breeds have been recognized by the CFA. However, the cats have been granted a place within The International Cat Association's show circuit under the subcategory of "Advanced New Breeds".
Maturation and Size of Large House Cats
Many large cat breeds can reach extremely heavy weights of over 25 pounds, though such weights are limited to precise genetic lines. However, most of large cat breeds take several years to achieve maturation. The typical time needed to reach full stature is between 3 to 5 years for almost every large sized breed. Judges do take maturation time into account during competitions.
Considering Large Domestic Cats
If you'd like to adopt a large domestic cat, you'll want to keep the following factors in mind.

Large Cat Breeds Are Loyal and Affectionate
In these ways, many large cat breeds almost mimic the reputations of canines. Breeders have often compared felines such as the British Shorthair to man's best friend when it comes to the protective and dog-like loyalties of these cats. The American Shorthair is famed for its amicable nature and hunting abilities.
Buyers who are looking to purchase a cat in lieu of a dog may do well to investigate the similarities between the larger-sized cats and their canine competitors.
Large Domestic Cat Breeds Have Special Needs
