My cat's lip is swollen after having kittens. What should I do?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 1 year and 7 months old

My cat had a litter of 6 on the 27th of Feb and all kittens are healthy. However I noticed today that her bottom lip has gotten quite swollen, and I don’t know if it’s due to licking her kittens too much causing an infection. What should I do?

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.
