Hi. I have an outdoor/indoor cat who is a persistent hunter. I'm so fed up of discovering mice alive and dead that I'm thinking of keeping her outdoors permanently or turning her into a very unhappy indoor cat. I've been through 12 collars this year but they don't last long and only have limited effect. She lived in a barn before I got her so I knew she may hunt but the mouse problem is incessant and I can't cope with finding any more mouse nests from when she brings them in and lets them free. All advice welcome, even if they were always dead it would be better than what we have now!
