I have only used the rat box traps before, and I'm wondering if the cat traps are the same, or if you can set them not to go off, so that you can get the cat going in and out, and then be able to predict when you are going to catch them, by setting them to close on that day. If not, how long does it usually take before a cat is trapped? I am keeping the feral full of food, to keep her in the barn, as she was nearly killed by a pack of hounds yesterday, so she is not going to be hungry enough to go in a trap I fear.
