Hi Mica, first of all, feel free to join and post the request in this group so it doesn't get lost in the front page feed as it fills up: https://opensimworld.com/groups/1060
Secondly, Fred has a cat follower companion which is likely on his welcome region here: www.outworldz.com:9000:Outworldz Welcome
Thirdly, There might be some others in the animal area of Bob solo's grid: avirtualworld.org:8002:trails
Best of luck!

For a moment there I thought you said "resizeable" cats - SCARY! :)
