Being this is a survival forum, consider the cats a test case. The largest Havahart live trap will work on everything from small mammals to birds to cats to medium sided dogs.

The catching is not the hard part. Emptying the trap can be a problem. Skunks, for example, are the only animal that demands some thought and planning BEFORE you set the trap! If you set traps for cats, you will catch skunks!

Letting an animal out alive can be quite dangerous without experience. Bobcats are about the most dangerous. Beavers and birds are about the easiest.

With a little practice, the Havahart and a crockpot can be your friend. Add CB caps to the ETS list if you want to be quiet.
