Fluffy either seems to ignore her or just thinks its a game and chases her back. Once or twice she has squealed in which case I have separated them for a bit. No fighting, no mounting or avoidance, just chasing and rumblestrutting.
Scruffy is fine otherwise. Doesn't stop eating and putting on weight each week, Normally about 1-2 ounces.
There is about 12 week age gap between the 2 of them. Scruffy being the eldest.
Thank you for your answer - it makes sense. I was concerned about the ovarian cysts as I had read about them on the internet and was worried it my be that. Could you just answer me one more thing? If this is dominance behaviour how come scruffy didn't start this behaviour straight away or is it because she came on heat and its being prolonged from that?
