I do have a half dozen of those traps, in three different sizes. When I lived in CA, I used them to trap feral cats, catching a total of nine on a property I'd bought. I hauled them off to the local animal shelter.
A good month later, the former owners called to tell me that they'd left their beloved cat Beelzebub behind and to please be sure to feed him. I said I would, of course, but from their description I knew it was the first cat I'd gotten rid of! What sort of a person leaves his "beloved" pet behind, anyway?
Sportsmansguide also sells the inhumane kind of traps, in sizes that go all the way up to bear traps. I always figured on buying one or two but never did.
