>From: tim fowler <[log in to unmask]> >Subject: jill in heat >I must just clear this up. Actually, I think you confused things. >The jill in question will not 'bleed to death' if left in heat for too >long. No. She will not "bleed to death". However, jills staying in estrus longer than 1 month are at risk of developing aplastic anemia. They could suffer from anorexia, depression, lethargy, swollen vulva with discharge, vaginitus (vaginal infection) among others. Jills become anemic due to the loss of red blood cells and her bone marrow will be severaly suppressed. In most cases, the anemia is not detected until it is too late. There is little hope for a jill with estrogen induced anemia - blood transfusions are necessary and only work a very low part of the time. Aplastic anemia will result in a death that is very painful. In the book written by Dr. James G. Fox (Biology & Diseases of the Ferret) states about aplastic anemia: "Hemorage is the most common cause of death" and; "Ferrets are typically in estrus for 2 months before death occurs". >Here in the Uk we all own ferrets that have not been 'done' I have owned >ferrets for 15 years, working them and breeding them.

I use a >vasectomised hob, which will knock her out of oestrus without the >resulting litter of kits. V-hobs are excellent. However, a jill that is not intended for breeding should be spayed. A jill that has a hormone injection or has been put with a v-hob will go thru all the motions of being pregnant. Weight gain, hormonal changes, emotions, molting, etc. This in itself is hard on the jill. >In your case, Matan, i would look at the mating prosess.

From eveything I have experienced and read, this is exactly the opposite. It is the penetration that releases the ovum. >Does the hob do it properly?

He'll only give her a jab to >put her out of season. I would try another hob first, if your are really >keen to breed a litter. Yes - he will hopefully bring her out of season. This may be for the best if she has not "caught" naturally. You could then use this time (her false pregnancy) to see what having a pregnant jill is like, learn a bit more on breeding ferrets, and save your jill's life by *not* letting her suffer with possible aplastic anemia.
