There is a pretty tame mother and 4 kittens (eyes are fully developed and they move around quickly) that are under one portion of my deck. I've been trying to lure them into a Tupperware container with bits of chicken, but it doesn't seem to be the ideal trap. Is there anything else I can try, apart from purchasing spring traps from a hunting store? I want to make sure these 4 babies are healthy and safe.
