We got three kittens from a rescue home two months ago. They claimed all three were 12 weeks old, making them all now 5 months. Friday is our scheduled appt for spaying and neutering (yes, 2 are males, 1 female). The female has been meowing excessively the last day. Hubby has noticed that the once, one of the boys did a mounting type move. She is laying on the bed rubbing on her side, and also was just now sitting with a rump in the air type position. Please tell me she is not going into heat. Helppppp
