I have SIX ferrets.
They DO not stink unless they are sick or not properly cared for and their glands don't have anything to do with whether they smell or not. If a ferret still has their glands, they may "poof" when frightened or startled. That DOES have a stink to it. Bathing ferrets makes the smell
worse. Ferrets shouldn't have a bath more than 1 time a year, unless they get really really dirty.
Rice boxes are great with keeping ferrets clean in between baths. They like to play in the rice, will dig in it, and the rice absorbs some of the smell oil from their fur.
Ferrets need rabies and distemper shots. They are also prone to certain diseases, like Adrenal (one of mine is). Adrenal ferrets have a smell to them. Some describe it as burnt popcorn. These ferrets sometimes need Lupron injections or adrenal surgery (removal of the adrenal gland).
Insulinoma...which is a type of diabetes in ferrets. This needs treated with meds.
Enlarged spleens resulting in surgery to remove the spleen. This is not a cheap operation. It can cost anywhere from $200 to $600!!
Ferrets need weekly nail trimmings. Ferrets need constant supervision when let out to play. Ferrets should NEVER be left unsupervised with children for both the child's and the ferrets safety. (member on a ferret forum I belong to recently lost a ferret because their five year old drowned it!)
Ferrets need a high protein diet...mostly made of meat. Ferrets should not have grain/corn products. Nor should they have chips, chocolate, sugars, etc.
Many people live or raw feed their ferrets. A whole prey diet is ideal. If that is not an option, than a high quality ferret kibble is a must...and a 4lb bag of high quality kibbles is at the minimum $15 a bag!! Natural Gold is $30
Ferrets can be litter box trained, but they also like to leave their packages in shoes, in corners, or as revenge on the walls.....
Cats and dogs can hurt a ferret.
Your ferret can KILL and eat your pet rabbit (this is a natural food for them after all) assuming a person with a ferret has a pet rabbit that is.
Ferrets are a high maintenance pet. They have a lifespan of 8-10 years on average. They are a HUGE responsibility.
Ferrets don't sleep on pine or any other woodshavings. They like cloth hammies, sleep sacks, or any dark place to sleep in. (check shoes often!)
They can fit into very small spaces! Homes should be ferret proofed for them to be able to safely play out of their cage.
My ferrets get 4-8 hours out of the cage a day. We have one that bites. I scoop their litter box 3-4 times a day. I feed 8n1 and Totally Ferret kibbles. I make them weekly soupies. They get ferretone for treats and their weekly nail trim. I also make all their bedding.
