If you mean a cat, no. Indeed, she's very happy right now because her brother is still walkabout (for the last three years he's taken off for months at a time, preferring to live rough as long as the weather allows). She's going to be furious when he comes home for the winter and might well murder me if I dared introduce another feline into the household.
Hey, it's just a mouse or two. Those who are infested deserve sympathy, not I.
