The largest breed of domestic cat is the Ragdoll. Scientific studies have compared and examined both a cat's brain and a dog's brain. The results established that the cat's brain is more similar to a humans than that of a dog. The cat's body contains 245 bones, but as they age some of the bones fuse together and the number of bones decreases. Cats have only thirty teeth.
Kittens have baby teeth which are replaced by permanent fangs at around seven months of age.
A cats hearing is incredibly sharp. They can recognize their owners footsteps from hundreds of feet away. The roughness of a cat's tongue has a very useful purpose. It gives the cat an extremely effective grooming tool with which to clean their fur and paws. The cat is one of nature's cleanest animals.
