I've had my cat for nearly three years, she followed me home one day all skinny and full of fleas, but gorgeous and sweet and bloody LOUD should have given it away then that she'd be demanding
I fed her as she was starving, door knocked over 100 houses, checked to see if she was chipped, rang every rescue in a ten mile radius, put ads in the paper and on the internet and still no-one claimed her.
Due to the rescues being chock full (it was the height of the recession) no one would take her in so we kept her whilst trying to find an owner, anyway it never happened and she wormed her paws under the table quickly.
We took her to be spayed and she'd already been done, she has never scratched anything (well us when we tease her, but no carpets etc), she was house trained, litter trained and everything. I still cuddle her and wonder who she belonged to and do they still miss the little demanding tortie that's so adorable, or is it as the Cats Protection suspect, she was dumped because of the rescues being unable to take her.
If you have rescues etc, or you've just adopted a cat, do you ever wonder what their life was like? I'd never part with her now (and she's chipped etc) but I do still worry someone somewhere is missing their furbaby.
