My cat's mouth is swollen, but she's eating. Should I worry?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | unspayed | 1 year and 2 months old | 12 lbs

I noticed some swelling or something on the side of my cats mouth and I was just wondering it was or if this is something I should be really concerned about. I’m at college right now so I can’t really get to a vet until the end of next week. She is still eating, drinking, and playing like normal. Is she in danger or is this something an over the counter kitty antibiotic can fix?

Thank you for submitting your question regarding Korra. I recommend that she sees a veterinarian as soon as you are able. The lip is swollen and possibly ulcerated. This is likely uncomfortable for her. The veterinarian will examine her especially looking inside the the mouth. She could have further wounds in her mouth or even a bad tooth. Treatment will be started based on these findings. I do not believe an over-the-counter medication will help. Do not give any over-the-counter pain medications either as they are toxic to cats. I hope this information helps!

    Hi and thanks for your request. In order to give you a specific and precise answer It would be necessary in this case to have some additional information about both the medication used and the reason for its use and a pic of the swollen area. Please send all this to our customer service email address (on main page of our website).
