She has mice in her kitchen. I had mice once, and my (very lazy, elderly) cat killed one and the rest moved out! Sadly, lazy elderly cat is now eating salmon and turkey in heaven and I got two cats from the RSPCA, a brother and sister from the same litter. The girl is an amazing mouser. But would it stress her out (the cat!) My neighbour has a dog and although she's very old and doesn't do much other than the occasional half hearted woof, i don't want to cause her stress. Any cat (or mouse!) experts?
