answer:From what I know about felids, they tend to spray their urine in order to mark territory and for other various means of communication. In fact, next time you go to the zoo and watch a tiger, you may notice that the genitals of the male sometimes face backwards – this is so he can spray the urine around. Are you asking about domestic cats? I’m not sure what the exact behavioral mechanism is that underlies a domestic cat’s proclivity to cover up its own wastes. Any felid biologists on here?
