I have a male Siamese, Simon who lost his sister almost three months ago. He yowl's all day long and wants attention all of the time. (he was very vocal before, but not this bad)I tried introducing him to another adult cat and he attacked her. He really wasn't very nice to his sister either, but they did cuddle together and play once in a while. I work from home so I can give him lots of attention, but he still seems unhappy or bored. He loves stroller rides but the snow will be coming soon. I thought about getting a new kitten, but don't know if it would help or hurt. Any suggestions?
