O.K. I got my new kitten today and I love her(no pics yet). Let me say this so you all understand, I know NOTHING about cats, and this is my first Sphynx. I'm thinking she may be in heat? She is VERY friendly,I mean VERY friendly. I know that Sphynx are friendly but like this? She is rubbing all over us and flipping her tail a lot. She was shy for maybe 2hrs and is now running allover like she has been here her whole life. How old do cats have to be to come in heat? I think she is to little still. She will be 6mo on the 9th of Feb. Can they fix her if she is in heat? I have no Male cats so that will not be an issue. I was going to take her in next week to get fixed. Maybe that's just the way she is?? Help!!!!!!
