Poorly cat

Sparkle has been poorly for a couple of days. Took him to the vet this afternoon and he found his back left leg is swollen and he has a high temperature. Antibiotics and painkillers.
And lots of cuddles !!! He should pick up in a couple of days and be back to his usual self.
Vet reckons another cat has scratched or bit him. Not much I can do about that. Cats will be cats !
