My cat has a new bump after surgery. Could it be an abscess?

Updated On September 23rd, 2025

Pet's info: Cat | Siamese | Female | spayed | 8 years and 7 months old

Is it possible for an abscess to form after a surgery to remove a mass from a cat? My 8 year old cat had a medium sized bump removed and the vet said he was able to take it all out. However, soon after the surgery, a new bump began to form in the same spot. Months later, it burst and a clear fluid came out, followed by small bits of a yellowish thicker substance(see picture).

Yes it is definitely possible for an abscess to form if there was any bacteria that was introduced underneath the skin in this area. It is good that it is draining, but now Luna needs a short course of antibiotics prescribed by your vet to get this to heal well. Also having it flushed with an antiseptic (usually we use Chlorhexidine solution diluted) will help this help well. I am sorry that Luna has this complication following surgery, but hopefully you can get this to resolve soon. Best wishes and take care.
