I knew that, ollie loves meat. What else can you tell me?
Thats very interesting, another fact about them is that they are often called house cats when kept as indoor pets
My neighbor has two cats - they've never even been out on her porch. What a weird lifestyle, don't you think?!
I am not sure. Unlike dogs, they do not need to go outside.
