amb5l writes "My new home has a small, natural pond in the back garden, which is home to numerous fish, Great Crested Newts and a small waterfowl community (mainly Moor Hens). Unfortunately, my cat has a well developed hunting instinct, and when I move there is going to be a massacre unless I come up with something to deter the cat from visiting the wildlife around the pond. An early grave for the moggy is not an acceptable option (my daughter will defend her to the death), neither is a 30ft wall. Do Slashdotters have any useful suggestions? I need something subtle and effective to enable the wildlife and the cat to coexist without bloodshed. While I'm at it, where do you guys stand on the cats vs dogs issue?"
