Ok here I go again....we had 64 spayed Dec 9 , at 5 months old..3 weeks after that she rolled around on floor, meowed real loud and stuck her butt in air, this lasted about 3 days....now this week she is doing again (the end of feb) So I took her to the VET where they ran a blood test and said her levels were normal....so my question..Is it normal for a cat to meow real loud, roll around on floor and stick her butt in the air when you scratch her back ?
