Pregnant female showing signs of oestrus?

Dear all,

I would like to know if any of you have had similar experience.

Abouth a month ago a friend of mine, a beginner breeder called me to ask why her pregnant female shown signs of oestrus. I told her that a pregnant female will not show any sign of oestrus, so it could be false pregnancy. But the cat did give birth to a litter of two healthy kittens two weeks after showing the signs of oestrus!

Just now I am having the same problem; if it could be considered as a problem. My pregnant female expected to due on 5th of June has been showing signs of oestrus the last 3 days.

I was very much concerned for all my other females always maintain their appetite very well until the end of their pregnancies. While this female I am talking about refused to eat anything when she was having her last oestrus right before I mated her with my male. Thankfully she is still eating, although not as much as before showing signs of oestrus in the middle of pregnancy.

I have two breeders of different breeds (one works with munckins and the other works with abbysinians) sent me e-mails telling that their females do this very often. One of them even wrote that her pregnant females show signs of oestrus more often that not.

Regards,
Yukie
