I have a small family of squirrels who have been hell-bent on destroying my backyard. Despite all their destruction, I could bring myself to catch and kill them. All the other catch and release traps were not good for squirrels, despite saying so. This one worked exactly as intended. These squirrels were clever, so I was worried they would pull out the bait instead of entering the cage, but the holes are small enough to encourage entry. Releasing was enough, though I did accidentally let go of the trap door when trying to release once. Hence the subtraction of once star. I would add a way to keep the door open that doesn't involve having to do so manually. Other than that, LOVE!
