My cat has a swollen lip for days. Is it serious or an emergency?

Any lumps/bumps that you notice on your pet should be checked out by your vet. Lumps in this location can be any of these things: * abscess (infection) * cyst * cancer (benign or malignant) * rodent ulcer I suggest you find a vet to take him to for an examination. There are no home treatments for any of these possibilities. Also, treatment depends on what the lump is - all those possibilities have different treatments.

The picture doesn't look like a very serious wound to me. I would continue to watch it. If it starts bleeding, if the swelling gets larger, if there is a creamy yellow/white/green discharge, or if Venus is not eating well, she may need to see a vet for treatment.

Yes a spider bite can cause a swelling. the swelling does not look very extensive so likely was not caused by one of the "nasty" spiders such as a black widow or a brown recluse. If your kitty, however, starts getting abdominal pain (rigid belly) or the swelling starts to change color, then a visit at the emergency room is the next step. If Maisey eats, drinks, lets you touch the swelling and otherwise does not act ill, then I think you have nothing to worry about and the swelling should go away within a day or so.

Hello and thank you for taking such good care of Rosie. I really appreciate you taking the time to submit pictures of her lips and mouth. Cats can sometimes get the same kinds of mouth and lip diseases that people get. Perhaps she bumped it against something or scraped it on rough surface as she was being curious. Another reason for swollen lips are possible allergic reactions to insect bites or noxious substances. In addition, dental disease or improper teeth occlusion can can cause lip abrasions. My best advice is this: As long as she is eating, drinking, and playing normally, give the lip 3 days to improve and get smaller. If there is no improvement in that time, or if the lip gets bigger in the meantime, please have her seen by your veterinarian for a thorough oral examination. I hope this helps. Thanks for your question.

Hello. This is a mild allergic reaction to something. It may take a few days to a week to go down, but if it does not, or seems to be getting larger, please see your veterinarian. Thanks for contacting Petco Pet Education Center, formerly Petcoach.

This could be the beginning of a condition also known as "rodent ulcer", it's basically an autoimmune reaction and it is not surprising if it starts to occur around pregnancy time. at the moment as long as it doesn't bother her and it doesn't become much larger, i would recommend just monitoring it, as treatment for this condition usually involve steroids which you can't give to a lactating mother.

From the photos it looks like Xena has a "rodent ulcer" (aka: eosinophilic granuloma complex). It is best to have her checked out by your regular veterinarian to get a definitive diagnosis and treatment. ( https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4951528 ) Hope this helps.
