Calvin is about 6 years old, he is neutered and declawed in the front. He hasn't had vaccinations in a while because he is an indoor cat and never goes outside. I have two large dogs and they are always kept separated because he does get scared of them and will run and hide. We had a little kitten for a while and he was ok but just wary of her because she had so much energy, so I think if he had to be around other animals, maybe an adult cat or two would be ok. He loves attention and will climb up and cuddle up right on your lap. Also, he is litterbox trained and has been since he was a baby.
