Hi, Jade, sorry to hear about your problem, but as the others have said, it's in a cat's nature to hunt. I have 5 cats (4 females & a male), the 2 youngsters are exceptional hunters (the others are getting a bit too old to be bothered now!). What I do, to minimise the carnage, especially at this time of year when there are lots of baby birds just fledging, is that I don't let the cats out in the morning till about 7o'clock - by that time the birds will mostly have had their breakfast. Then I get them all in again when I go to work and they stay in all day till I get home, I then let them out at about 4.30 till they come home for supper (usually 7 or 8p.m.) and then I keep them in for the night. This stops them hunting at the times when the birds are most vulnerable and by keeping them in at night also negates the risk of them getting injured or killed on the road. Although we're very rural here, we still get the odd idiot who uses the road by the farm like a race-track. Hope this helps. Good luck (by the way, is your cat neutered? If not, get him done as it will stop him wandering), K xx
