My Cat Doesn't Like His Neighbor
Kuhla, our 5 year old male tabby, came to our home a little less than a month ago. He's a great cat and all, and he still is. The problem arose a couple days ago when a black cat comes to our yard. Kuhla is an indoor cat who didn't ask to be let outside even once since he came to our home, although he does like to look outside the window a lot.
We do know that there are some cats in our neighborhood, but we'd thought that since we're not letting him out, that shouldn't be a problem. But a couple of days ago, he saw one of the neighbor cats for the first time. He was fine with it (I didn't know if it was a he/she). And then a day or two later, a black/gray tabby showed up, and he was fine with it too. He just meowed to us gently whenever the those two cats came by and they'd just look at each other for a long period of time.
However, a couple of days ago, a black cat showed up, and Kuhla started to get pissed off. He doesn't even growl, he SCREAMS so loud whenever he sees that black cat, and he would try to claw him (well, he couldn't because all he does was claw the window). Does this happen to your cats? What should I do about it.
