Sorry....aibu.
My eldest cat is a bit of a fighter. Regularly gets bitten on the leg, I see her limping, take her to the vets and hand over £70 for antibiotics for an abscess. This time, I noticed a scab on her head so no limping to tip me off that anything was wrong. She seemed fine, eating and drinking normally. Tonight I noticed there was a swelling that had developed. It was squishy so I removed the scab and I've drained the puss. She sat and let me do it, only getting grumpy when I bathed it in salt water. Do I need to take her to the vet? She seems fine. Can I just keep an eye on it? Going to the vets traumatises her. I would take her if she seemed like she's in pain, at the moment she doesnt. Wwyd?
