over the last 30 plus year's mah mother has had around 20 cat's so this is not uncommon at her house. it is however infinitly funny because regaurdless of there condition she is deathly afraid of mice, rat's etc.
Ours brought home a squirrel. Live of course, and missing its tail, so after we were done getting the blasted thing out of the house we had some nice blood splatter across the walls and furniture to clean up. Delightful afternoon.
