I have a cat that can handle weasles. She is not very big. I think she weighs about 6 pounds, but boy she is a good hunter. Her name is MaCat. She adopted us and has lived on my front porch since last summer. We were going to rehome her after she had kittens on my front porch this spring, that was until she started bring us mice that she had caught. After taking her kittens and having her fixed, she went into over drive on the hunting. Along with a half dozen mice almost every day on my front porch, she caught 4 weasles. Three had bodies that were about 8 inches long plus their tail but one had a body that was about a foot long plus the tail When I saw her trying to carry that one across the yard, the best she could was drag it 5 or 6 feet then drop it and get a better grip on it and drag it some more! She has a sweet disposition with us but I wouldnt want to be a mouse or weasle!
