Looking For A Pet Sitter For 1 Cat In Charlotte

I'm looking specifically for behavior training for my 4-month-old kitten. Specifically aggression towards my older cat who does not seem to want to play. The kitten was found at only a few months old, And was separated from his littermates just a couple weeks after that, so I don't think he had much time to learn how to "play nice" and I don't think he's learning well from my older cat. My older cat seems to care for and accept him, as I've seen him grooming him and being careful when they fight, but I don't think my kitten realizes how bad he's being
