I have several former ferals that are good mousers, and believe it or not, my CH kitty Diva has caught a couple. Mittens, a former foster, was an awesome mouser, with those catcher's mitts of hers.

The best mouse story from my place comes from last winter. Six of my cats had this poor mouse surrounded in my front hall. Nobody would go after him so he got away! Later I saw 4 cats staring under the fridge in the kitchen. The next morning I found a poor little dead mouse in the kitchen. When will they learn that this place is feline central??
