hi everyone... One thing that has worked successfully for me is the TrueAir system. It costs about 20 dollars, but it works pretty well...But you have to plug it into an outlet which is a pain, and often times, it's overwieghted, so it comes out of the outlet...not only that, but you have to have it in an outlet that's not farther than six feet of the source of smell(fortunately I have an outlet about a foot away from the cage and wastebasket). And lastly...I recently went on a little vacation(1 week) and when i came back, my 17 wk old ferret, Kit Kat, had drastically gained A LOT of weight... It's really amusing, but i don't think that females are supposed to get this big..she's runnin about 2.2 lbs. She did lose a little of her spunk and hyperness, but she's still definately herself...she also lost her "hood" and now has become a true black sable with a black nose... should i worry about her weight? dooks, darrin and the ferts [Posted in FML issue 3501]
