Sooo... a kitten just showed up on my doorstep and he's the greatest except that he tortures my adult cat! She's not super old (almost 4), and as a kitten she had a playmate, but she's been the "only cat" for a while. They've gotten to the point where they can co-exist, share litter box, water bowl, etc., unless the kitten is in hyper-mode which is when he just attacks her all the time! The vet thinks he's about 8 weeks old now, so I'm afraid it's going to get worse before it gets better... I've had him for a couple of weeks, and as much as I love him, it makes me sad that my adult cat doesn't want to cuddle and basically sticks to herself all the time now. Advice?? I definitely did not choose the situation I find myself in, and I'm afraid that the age difference is too much to overcome..
