You have the worst kind. The sneaky kind. Cats are instinctive killers. Those who hide their instincts are E-V-I-L, and I wouldn't trust them.
We have a new cat from the rescue pound. A little darling, and now she thinks she's a hunter. Hasn't caught anything bigger than a cockroach yet, but she sure is trying, and she's a hoot to watch in the back yard. One mockingbird dive bombed her, smacking her in the butt, and she decided that was enough fun for the day, and spent the rest of the day in the security of the couch.
It's a jungle out there.
