can you please tell that to my cat is it has a tendency to bring them home to show and tell ,along with fucking rats and other little cute things, it has murdered ,touble is two of the snakes were still alive and very pissed off being left at my back door. p.s also does not fuck with my plants , nor does my bull mastiff that keeps other cats and most living creatures away , as far as birds they may shit on them ???. or you could buy a pet falcon or something that would solve the bird probem ,and maybe the cats , or i will rent my dog , it hates most things that move.
