My cat had abscess surgery. Why isn't her drainage tube draining?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed

My cat recently was taken into the hospital after a run-in with an opossum. she had bad injuries and the doctor said she needed surgery due to an abscess. she's been home two day now but the work seems a little.. off. The doctor said she would have a tub put in her to help drain any fluids but it there has been no drainage and the 'tube' seems to just go right through the injury- we'd like a second opinion so we can take her elsewhere is needed

The tube is a drainage and seems well placed. If there is no fluid coming out from the wound the tube can be removed in the next 48hours.
The wound seems, externally, healing quite well so if Luna is ok in herself (eating well, no lethargy, no vomiting or diarrhoea and no excessive discomfort), everything seems going well postoperatively. The outcome will be good, and I do not think you need to seek advice from another vet.
I would discuss Penrose drainage removal with your vet and continue with medications prescribed (antibiotics are needed).

Differentials include skin cysts, infections, benign or more sinister type of tumors.
