Its hard to tell because she always seems to be breathing hard! She is doing alot of up/down/up/down. showing some other signs too like flehming, looking at tummy, tail swishing. Her vulva looked swollen and loose when i checked her earlier and she REALLY did not want me touching it. But then again she has given us all these symptoms before and produced nothing! I really think she just likes my sleep deprived zombie look!
