Ours occasionally comes along and licks the milk at the bottom of our muesli bowls. And she's much better at dealing with the mice than the traps. She also spends a lot of time sitting on the internet, acting as some kind of firewall I think.
We've recently discovered that there are at least two other cats in the building, which could be why we saw a flurry of mouse activity before we got ours.
I have just discovered that our cat likes icecream. As regards chasing mice he is a pacifist. The other day he was seen lying in our garden with a dormouse nibbling a fallen apple about 30cm from his nose.
My cat presented me with a very much alive and wriggling mouse yesterday. It was a great big ferocious critter, probably weighing well over a quarter of an ounce.
