I will start by saying my cat is an excellent mouser. In fact he is so good, he has become the heaviest cat I have ever owned since we got the chickens, rabbits & quail. We have plenty of mice & long story short, He is getting fat! We stopped feeding him & he still hasn't lost any weight. Putting food down is a waste of time since he is full. Obviously full on mice he brought this young (about 7-8 weeks) male field mouse into our flat & left it on the kitchen floor in shock stumbling about. Needless to say, it had a lucky escape because I nearly trod on it on my way to the kettle. I bent down & scruffed it & put it in a bucket with some rabbit food & some loo roll. Its now snuggled down under the loo roll & has perked up. Now I don't know whether to collect a mouse cage for it or stick it back outside. I don't want to give it the cat since he's never really hungry & will just toss it about for ages causing needless suffering. We don't have any snap traps or anything since we don't like trapping mice to kill. I also don't want it back in the garden, breeding & eating the animal feed (which we keep in the flat anyway to stop mice helping themselves). Before anyone says shoot it, I would but its illegal to have guns. Really all I could do is drown it, but I don't do that to our animals & I don't see why a wild animal should suffer any different. I'm also in a town with nowhere to release this poor guy without him causing problems. Also I think it would just get eaten. Also the temps here are currently below freezing. I've raised baby field mice for release before, but I know they need a tank with lots of hay & privacy. I don't mind it as a pet, but what about disease?
