In 7 or so days,I've taken in 5 ferretsJust got a call to maybe take in another 4.That would mean 23 in my 2 br apt,which is where my shelters located.Hoping to just educate these folks that have the 4,get them to keep them as they really do love the guys.The ferrets were dumped on them. Wish me luck. As for odor control,I have a Pollenex Humidifier/air purifier that runs 24/7 in the ferrets room.I also clean litter boxes twice,use pine pellets,the safe ones.Wash their bedding 2 times a week.Vacume floor everyday.I also have plug in(oil ones) in all the rooms except the ferrets room.My place was inspected recently & given a +.Hope this helps.
