As another reviewer mentioned, it is somewhat small, and probably better suited to squirrels and rabbits than anything bigger. Seems small to use for most cats. Certainly would need to be checked frequently to not harm the animal. It is sturdy enough to contain animals that fit in it, and was effective at capturing my target animal it's second night in service. It is worked, and is easy to use, but left me pondering some of their mechanical design choices. I would like to have seen a means of opening the door to release the animal that provided greater separation from my hand and the frantic animal. If I have need to use it again, I think I will rig a means of pulling the door open with a light cable or cord. In the end, it was effective, competitively priced, and did the job I needed done.
