A cat would be the EASIEST animal to trap. At least mine would be. They are so predictable. The newest box in the room will have one of three cats sitting on it within a minute. Never fails. An open cabinet door is immediately irresistible to them, more so than catnip. Same thing with a coin door. I open something up and they show up out of thin air. One day we could not find one of the cats anywhere. She always tries to sneak out of the house. I had an idea to see if she was still in the house. I went into the game room and opened a coin door and she came running up and jumped inside the machine. "Found her."
