My kitten has been acting strange lately. She moves around with her butt on the ground, in a humping motion and she meows alot while doing it. I have no idea what it could be. She is not fixed, could she be in heat? How much does it cost to get a girl cat fixed?!
This sounds like her anal glands are bothering her. She should be seen by the vet to have them expressed. Cost varies, call your vet. vetcare
