I was getting dressed this moring and Mooch and Noodles were wrestling like usual. Well Mooch came into the room where I was and was kind of crouching down and chirping as she walked. Then she has started lifting her rear into the air and kneading with her pack paws all the while chirping. Is she in heat? They are both scheduled to be spayed on Tuesday. I was on the phone with my mother when she started that so my step father got on the phone and he thinks it does sound like she is in heat. Fortuantely Noodles is just looking at her like shes nuts. (They are sisters.) If she is, what do I do!?! She won't come into contact with any males. They are just now 4 months old too. Any advice will be most appreciated! None of my cats have ever gone into heat before I've had them fixed, and most weren't fixed till they were 6 months. Please help!
