well ime unconvinced i dont care how well trained a cat is unless it has never stepped foot outside the house no one no matter how good an owner can account for its whereabouts or its actions when in other peoples property
if my child walked into your yard and took a crap me saying but he usualy uses his potty or burries it in his leggo wouldnt make you feel any better about it i dare say
maybe i should start returning the cat crap to its owners via their letterbox
ps:
people who let their dogs crap everywhere are just as bad but at least a dog dosnt jump over your wall , take a crap and ****** off
