Hi, folks. I've been on this list for a long time now, but have been a lurker for most of that time.... My little Fert, Kaos, is not so little this winter. He's added about a 1/2 to 3/4 a pound to his 3 pound frame. I know weight shifts are common, but this seems excessive. Are there any good web sites that you can point me too for suggestions on what - if anything - I should do? Do you have any? Thanks! Karl and Kaos Karl Muchow Partner CamLight Systems [log in to unmask] [P.S.] Folks, I read the ferret FAQs and it suggested that a 40% weight gain is acceptable in winter. Sorry about the previous post. I should've read the FAQ first. If anyone with experience thinks that a Fert that's otherwise acting and looking OK should NOT gain that much weight, please let me know. If it gets worse, I'll take him to the vet. Thanks!
