Hello, you are through to Dr Linda, a UK based vet.

Hopefully I can help you today.

Does Gucci go outside or live with other cats?

Is the bump bothering him?

Would it be possible to send a clear photo of the bump please?

Customer: replied 14 days ago.
We do have 2 other cats and he is an outdoor cat. The bump doesn’t seem to be bothering him, he’s still eating fine and when I touch the bump, he doesn’t shy away from my touch or seem to be in any pain. I just want to make sure it’s nothing to worry about. I’ve got a couple of photos, but the bump isn’t very clear to see. It’s at the back of his head under his left ear
Expert:  Linda Simmon replied 14 days ago.

I understand.

A new bump can have a few causes including:

  • A cat bite abscess (bacterial infection)

  • Insect bite or sting

  • Cyst

  • Fatty lump / lipoma

  • Enlarged lymph node

  • Seroma (accumulation of fluid after e.g. an injury)

  • Etc

If he is acting normal and you have just noticed it, I would monitor for a few days as it may settle.

Watch closely for signs such as head shaking, scratching, reduced appetite or lethargy.

If the lump persists, he may require treatment. To determine what it is, we might consider putting a needle in it and seeing what we aspirate.

Fingers crossed it resolves shortly,

This window remains open for several days so please let me know if there is anything else,

Great thank you, ***** ***** of the way he is acting right now, it’s nothing to worry about?
Expert:  Linda Simmon replied 14 days ago.

It is unlikely to be an emergency, correct. He does not need to see a vet tonight.

However, it may be e.g. an abscess, so if it persists or he becomes unwell, he would need to see the vet as he may need e.g. some antibiotics.

Hi, this morning I found that he has itched it and it has been bleeding. now there’s an open wound. I’m going to take him to the vet. And how do I make sure it doesn’t get infected now?
Expert:  Linda Simmon replied 12 days ago.
Wash with saline and use a buster collar. The vet will likely start antibiotics right away.
