How to stop my kitten from suckling her sister's anus and her own?

Updated On September 23rd, 2025

Pet's info: Cat | Bengal | Female | unspayed | 2 months and 8 days old | 8 lbs

I have two kittens, both female, both 11 weeks old from the same litter. One(Shiuli) is seemingly nursing on the other's anus. I've tried to stop her but it doesn't seem to be working. Even if she does stop nursing on the other kitten, she will nurse on her own anus. I mean nursing like suckling, not the ordinary grooming licks. Cotton(other) has kicked her in the face but she continues to nurse on Cotton while Cotton is asleep.

Unfortunately its hard to tell in the pictures if the skin looks abnormal. It may be that they have some irritation that is making Shiuli very interested in the back end. Are their stools formed or is there some diarrhea? Make sure they are eating a high quality kitten food. Ideally take them both to the vet so that your vet can determine if there is a physical health issue or is this a behavioral issue. Best of luck with them!
