This thread got me to thinking about this.
Housecats are very prolific breeders. My (very minimal) understanding of population biology tells me that the reason an animal would be that prolific is that most of the babies can’t be expected to make it to adulthood in the natural environment. Cats have other behaviors (burying waste, hiding when injured) that this site says are behaviors designed to avoid predators.
My question is, what animal or animals prey on housecats (or their wild ancestors) in their natural environment? If I Google “cat” and “predator”, I get lots of links about cats as predators, but nothing I could find on what preys on cats.
