Lost cat in Leeds — Alert #2070

Found this cat that's been in my garden for 2 days, no neighbours seem to know anything, I've taken her to vets as no collar, but sadly, no microchip. Vet confirmed she's female, probably old as she is missing teeth and the ones left are in a bad state. She was ravenously hungry, ill care for her for a couple of days while I seek the owner, then I will be asking a cat charity if they can help her. She is extremely friendly, but I am unable to keep her as my son is allergic to cats 😢
