I have a cat with a burst abscess - my vet cleaned it and gave her injections of antibiotics and pain killers and put liquid antibiotics directly into the wound. I asked if I should keep cleaning it and the vet said no. it's a large gaping wound on her neck. The vet said it would heal in around a week but it's been three days and it doesn't look any better (or any worse). The cat seems fine apart from the huge hole in her neck - she's eating and drinking fine and is not lethargic - and I'm keeping her indoors for now. How long do abscesses usually take to close up?
