A while ago Harvey (who is so fat he has to get through the cat flap one bit at a time) brought a huge rat in. I was really worried it had died of poison and he'd just picked it up, but a second glance at his blood stained nose told me he'd fought and killed it himself. Had it been a bird I'd have gone doolally as I'm scared of them, but I shoveled the rat into the bin. He seemed put out that I'd rejected his gift!
