https://www.vetsurgeon.org/f/clinical-questions/3899/ferrets-in-season We have 2 ferrets coming down who the owners think are in season. Seems to be wrong time of year is that right? Also other than swollen vulva, what are the other signs of oestrus in ferrets? en-USTelligent Community 10https://www.vetsurgeon.org/thread/10538?ContentTypeID=1Mon, 21 Dec 2009 19:07:22 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:3e433262-4334-4cfc-8a59-428e55bd0e6aIan Mostyn<p>With central heating and artificial light it is not impossible for them to come into season any time of the year. I would use th delvosteron with a vulval swelling as hyperoestrogenism can cause bone marrow suppression with low white cells as well as anaemia. The dose is 0.5ml Delvosteron and is printed on the side of the box. The other worry if they don&#39;t settle down is Cushings disease. In the ferret it is a disease of sex hormone production rather than cortisol,, is more common in the female and will cause vulval swelling and often alopecia. Diagnosis is made via blood sample for all 3 sex hormones (testosterone, oestradiol and progesterone) and labs will often have a specific ferret profile. A significant raise of any of them would be diagnostic</p> <p>Ian</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/10526?ContentTypeID=1Mon, 21 Dec 2009 12:15:45 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:e16ea7ca-0b76-4e60-a091-e73c598b1b27Rob Davis<p>I&#39;m no great ferret expert, but....</p> <p>Generally the vulval swelling is sufficiently obvious for their to be no doubt that they are in season. Have they been seen recently? Could they have been in season for a long time without the owners noticing? If so then anaemia may be a signficant risk. If they are in season, delvosterone is licensed for use in ferrets (0.5ml per jill I think, but check the data sheet); beware, it stings on injection!</p> <p>Hope that helps until somebody with more ferret knowledge than me comes along!</p><div style="clear:both;"></div>
