The threatening dog thread got me thinking about a problem we're having, though much less dangerous. The issue for us is several neighbors who are content to let their cats roam all day and night. As a multiple time cat owner, I love the things, but only when they are indoor only pets. Having other people's cats roam through my yard, crapping it it, walking on and scratching my cars, chasing/eating song birds, etc is pissing me off.
So far, I've tried:
- Talking to the neighbors
- Water guns
- Chasing them out of my yard
None of these have worked. Any suggestions?
