Help Trinity the Cat

Trinity came home crying and limping on 3 legs. She's only 2 years old and is highly intelligent. She loves playing fetch and figured out how to open doors by herself. She dislocated her hip and is in a lot of pain. She needs a femoral head ostectomy surgery that costs about £3500. She's my favorite cat ever, euthanasia is not an option. I'm asking for donations for her hip surgery, thank you.
