[citation needed] Non-neutered cats in the U.S. are three times more likely to require treatment for an animal bite. Having a cat neutered confers health benefits ...

Felines, especially domestic cats, are well known for having penile spines. Upon withdrawal of a cat's penis, the spines rake the walls of the female's vagina, which may serve as a trigger for ovulation. [4] [5] Many other felid species have penile spines, but they are relatively small in jaguars and pumas, and do not occur in margays. [6]
The trees also helped show that F. s. lybica gave rise to the domesticated cats of today. F. s. silvestris showed a very early branching away from the other groups, but still shares a very early common ancestor with the rest of the clades. [5] Domesticated cats originated [11] from near-eastern and Egyptian populations of F. s. lybica. The ...
