Hello all. I have a 8yr old cat and a new 3 month old kitten. My older cat is pretty accepting of other animals even dogs he doesn't mind. But upon getting the kitten he seems to run away all the time. At times they groom each other or sleep together. I put their bowls together for them to eat and drink together. But most of the day the kitten wants to play and it just ends up with hearing them run around the house and my older cat crying or hissing at him. There hasn't been any fighting as far as bleeding or something. But I'm not sure if this is normal or if i should do something more. The kitten loves the older cat he wants to be under him all the time and it just seems annoying to my other cat. Any tips or suggestions?
