I wouldnt be setting a body grip up on the home front if you have cats/dogs that you like.
if i need to rid something from around the house I usually use a live trap like the suggested havaheart.
You might not, but how many groundhogs do you catch?
I catch dozens every year, all in properly set bodygrippers and have never caught so much as a feral cat in one, and they are everywhere.
The trap needs to be fit into the lip of the whole and not just laid on top. Obviously don't set them where kids play.
