Heres the problem. My neighbor has a cat that is really mean. The cat lives outside and is able to go where ever it likes, which 90% of the time is my yard. It has already gone after my ducks on two occasions and Im sure it will try again. I have tried to talk to the cats owner about making it a house cat or keeping it in their yard but I was ignored. I cannot contact animal control or take any legal action because due to zoning laws I am not suppose to even have the ducks. The neighbors love the cat and would be devastated if it was hurt and I am an animal lover so killing the cat is not an option either. The only thing I can think of is to go to walmart and buy a low power airsoft gun and shoot the cat whenever it comes in my yard. It would not hurt it, it would just sting. I really dont want to do that either though. Putting up a fence is also not an option. So any ideas on how to keep the cat out of my yard.
