Our newly adopted kitten, Munchkin, has been trying to make friends with the established cats in our household. She hasn't had much success with our two females, Katie and Tinkerbell. When she approaches them, they just hiss at her. Tiger, on the other hand, is our mild-mannered male cat. So... Munchkin has chosen him as the most likely candidate for a friend. She began by chasing Tiger around the house. Now she has apparently decided on a less aggressive tactic.
Here, she faces him and they just look at each other from a distance:
Then she comes a little closer, and makes it clear that she is not going to chase him. I think it may take a while, but she is making progress... don't you think?
