Do male cats fight

Some male cats do hunt mice, but it depends on the type of cat. Most cats try to hunt them but some just play with the mice to have a little time off their hands. All domoestic cats hunt mice, it's an instinct as most domestic cats are individual hunters, unlike Lions. I see why you would of thought that, with the behaviour of Lions, But most cats hunt alone. Of course, I don't think fully grown tigers hunt mice. Maybe babies of wild cats, but besides that, I think only domestic cats.
yes, and trust me i have seen my cat eat plenty of mice.
