My cat came home last night crying and not himself. He kept wanting to sit down, his back leg seemed sore. Thought he might have been hit by a car. Phoned the emergency vet who said if his leg not obviously funny shape and not bleeding to leave him be and take to vet this morning.
Got appointment first thing. Vet says he has probably got a clot in his back leg caused by heart disease. Hes on strong painkillers and is staying in.
Ive googled. And I'm so sad.
