So, here's the story...
I have a spayed female cat
that stays in the house all the time. My neighbors have a non-neutered male cat who stays outside. The neighbor's cat sleeps at my back door, drinks from my birdbath, and brings me nice little presents. I even witnessed it catch at baby rabbit in my yard one morning. I don't enjoy these things, but I can deal with them, he is just a cat afterall. The big problem is that my cat can see this cat through our backdoor and even when he jumps into the outside windowsills. These two cats do not like each other and "fight" through the glass. On numerous occassions they have started a fight at my DDs window in the middle of the night, waking her up, and scaring her half to death.
I've tried a spray bottle of water and squirting the cat when I see him come around, but he still comes. Is there something I can put on the doormat and outside windowsills that will make him stay away? I've put vinegar in the trash before to keep the animals out of it, but I don't really want my backdoor to smell like vinegar. Any suggestions?
