I purchased my kitten at an animal shelter when she was 10 weeks old. I've wondered if possibly she was taken away from her mom too early. She tends to suck her own nipple, almost like she's trying to get milk. She only sucks one of them, but she sucks it quite often, to the point where it is somewhat swollen. She wakes me up in the middle of the night because the sucking is so loud. Telling her no doesn't seem to get her to stop. I've considered feeding her with a bottle, but I am afraid that will encourage the sucking. Any suggestions? I've taken her to the vet and the vet didn't really give an explanation or solution.
