My name is Nikolai!

We adopted Nikolai from Pet's Mart earlier this year. We already have a 4-year-old cat in our home and wanted to give him a friend. Nikolai adapted to our home very well. He likes to cuddle and he's very playful. He knows how to use the litter box. The only issue is that he tends to want to dominate our older cat. They are both male and I think it may just be an issue with that. He didn't attack our older cat but would chase him around the house and swat at him any time he gets near to Nikolai. It started to stress out our older cat, so we decided it was best to rehome Nikolai. Nik is good with dogs and probably would do well with a female cat or younger cats. He is playful but our older cat is not so much.
We did not have any issues with him other than that and he is in very good health. He has a really beautiful long coat.
