Just lost my post grrrrrrrrrrrrrr
I think you have a purrfect place for a cat
I woulde email any rescue you can find.............play on their emotions cos most have so many cats to rehome but dont let them play on yours!
Tell them that one of your cats has passed to the Bridge and her friend needs company and you are feeling so lost and can rehome a suitable cat and would love to give one a wonderful home for Christmas.
Do you drive and could you travel to pick one up?
The rescue that only googled you is just lazy and on the ground things are so different, everyone has a busy road somewhere close.
Loads of luck and dont let them play games with you, make sure any cat is healthy and the right one for your cat
