How can I stop my one cat from hunting the other?
From 2000 to 2014, we had two cats, a brother and sister from the same litter and they loved each other and got along great. So, after they passed, we got another brother and sister, but this time, the brother is frequently in pursuit of his sister and she is just not that into him. She growls and hisses. He perseveres. We engage him in play to help him get rid of some energy while helps while we're playing but not so much overall. Sometimes, I feel bad for him because it seems like he just wants to play with her (and we got two so they would have each other's company while we were at work), but I guess he's been too aggressive and she wants no part of him. Mostly, I feel bad for her because it seems like she just wants to be left alone and he can be quite relentless. Sometimes he gets a time-out, shut in a room by himself so she can have a break from him. Has anybody else had a similar problem?
