I remember those days. When we rescued Misao from the streets she was unspayed and very ill, so we had to wait until she was healthy before getting her fixed. Well she went into heat about 2 weeks before her spay date and man what an annoyance. She kept doing the "present butt" manuever to poor Terra and Terra had no idea what going on as she had been fixed long before ever going into heat. I think Terra spent the entire 2 weeks on top of the furniture and out of Misao's way.
