https://www.vetsurgeon.org/f/clinical-questions/28819/anorexic-ferret I&#39;m not experienced with the species tho I really like these animals. I have a two year old ferret weighting 0.98kgs (few months ago was 1.20kgs). Male not neutered but criptorquid. Has another companion, also male not neutered not displaying signsen-USTelligent Community 10https://www.vetsurgeon.org/thread/218980?ContentTypeID=1Fri, 24 Jan 2020 21:43:31 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:a54e2daf-0e7d-4f14-a3aa-95361384708ebevs2251<p>Usually need to heavily sedate/GA to get blood from a ferret. I&#39;ve usually been able to get 1-2mls from the jugular veins, unless very sick or dehydrated. Haven&#39;t attempted the cranial vena cava site. Use 22g 3/4&quot; or 1&quot; needles as ferret skin is thick and tough so smaller gauge needles are hard to get into the vein. Tail alopecia is common in ferrets, not significant unless starts losing from lower dorsal area. Beware foreign bodies in younger ferrets. I do full body check over uga in a sick ferret - bloods, urine, whole body radiology. Good luck.&nbsp; &nbsp;</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/218895?ContentTypeID=1Sun, 19 Jan 2020 14:48:13 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:8fc0fd83-ac19-4a7b-8419-0698676c5526Mark Rowland<p>Hello</p> <p>You need to get some blood really.
