I have never used one of these things since we live in the country and can take care of most nuisance critters without being patrolled by the area sheriff. If the animal is going into the trap but the trap is to slow to catch the animal I would look at the mechanism and see if there are any springs or whatever that could be replaced with a stronger supposedly faster spring. My biggest worry would be catching one of those racing kitties with a stripe down it's back. Don't think I would want to empty that trap at all.

Anyway, it looks to me like those big doors - even preloaded by slipping in sticks to hold them partway down, are just too slow once gravity takes over. More than looks like: even sitting inside hearing it trip as unexpectedly as the animal does, it seems like an awful lot of brain cycles go by before it actually slams to. > Anyone had any experience with (any) live traps? Any other tips or tricks? Thanks in advance.
