Lump at Anaesthesia Injection Site

September 3rd, 2003, 06:56 AM
Hi fellow pet lovers

My six month old healthy tabby kitten, Obi, was neutered one week ago. He has developed a very large lump around the site where the anaesthesia was administered. I have never had a cat neutered who afterward had a reaction of this kind. My vet has given me antibiotics for Obi, which he is to take twice a day. However, the vet said the lump may become an abscess that needs drained, or it may dissipate. In either case, I am concerned for Obi's general wellbeing. Will this infected lump 'leak' into his bloodstream? Is it a common reaction? Why isn't the vet sure what caused it .. eg infected needle? Please could someone help.
I had a rescued cat for eleven months, who died of cancer, and Obi was the little kitten I needed to love in his place. I don't want a healthy cat to become sick because of a routine castration operation.:(

Was he vaccinated at the same time?
Could possibly be a vaccine reaction, if so....

:) Many thanks carina .. no, Obi was vaccinated six weeks ago and there was no reaction to the two injections.

Oh OK...actually I originally misread your post and wrote a whole response about vaccine reactions! Whoops. :o I've never had an animal get a lump by the injection site, although female dogs sometimes herniate where they've been stitched after a spay & that's not usually a big deal.

Anyhow - sorry I don't have any other ideas. Maybe you could swing by another vet clinic just for a second opinion? It shouldn't become systemic (get into his bloodstream) - and if he's on antibiotics now, I wouldn't think it would abcess either.

Maybe you could do a search on anaesthesia injection reaction, or something...?

Hope he's OK!

Just wanted to let you know that Obi is doing fine.

The lump has all but disappeared, two weeks after the injection - with the aid of antibiotics.

Thank you for your help and support.
