A STRAY ONE!!
It started hanging around about a year ago and had I known it was going to adopt us, I would have given it a better nickname than Socks (black cat, white feet, nose & neck). She wasn't quite fully grown or else stunted from hunger and it took a few weeks before I realised that I couldn't even slide my finger under her collar...what sort of animal puts a collar on a kitten then stoips feeding it/leaves it behind?
I've since had her sterilised and treat her topically for worms, etc. She comes & goes as she pleases and a year later, she's still a tiny, boney little thing despite demand feeding her up to 4xday.
Sad really, I don't even like cats but I still care for her better than the person who went to the trouble of getting a kitty.
