Hind Motion Sensor Is It Normal For A Cat To Be Horny After Getting Fixed?

Is it normal for a cat to be horny after getting fixed? - hind motion sensor

When I go to bed with my cat jumped up and buried her nose in the blanket and knead. While the "back room picked" and seems to collapse is in slow fuck. I wonder if this is weird because I am the dissolution. He was 9 months, but never spray or anything. This happened to you?
