My cat has been chasing this mouse in our house for a week and we had even set out a trap for the rodent. She finally got it this morning and looked at me as if to say" well I finally did it". Punkie is not normally a mouser but I think she understood us saying that the baby duck could probaby catch a mouse better than she could and she set out ot prove us wrong. She can catch a rabbitt, squirrell, mole, and mice outside but would not deal withh anything inside.
