I had a cat when I was a teenager though – she adopted us! She turned up on our doorstep hungry and miaowing, we fed her and within a few weeks she was sleeping on our beds. She was lovely, completely grey and very beautiful.
I used to have a dog, but sadly she got old and died. She was great fun though! I’d like to get another, but at the moment, I live in a flat so don’t have a garden so there would be nowhere for the dog (or cat) to go and play!
