Let’s see…
I don’t know about all of the things that can go wrong healthwise with rabbits yet but Ferrets are prone to adrenal disease and insulinoma. Adrenal can sometimes be controlled with melatonin implants but insulinoma is expensive to treat. There are many other health issues such as ECE (green slimey poop), ADV (similar to FIV in cats), and dental problems.
Ferrets are stinkier than bunnies, even unaltered bunnies. They generally come already altered because females can literally die of anemia if they go into heat and don’t get pregnant. Males are very aggressive if they aren’t neutered to the point that you can hardly handle them. Plus they SMELL awful.
Ferret poo is way messier than bunny poo and they never 100% litter box train.
Ferrets are easier to do the monthly maintenance on. Nail trimming and ear cleaning are a cinch because with nails you can put ferretone on the belly (which is like CRACK) and they don’t even realize you’re doing their nails while they’re snarfing up the ‘tone. For ears you can scruff them, which is equivilant to trancing but leaves one of your hands free and kind of paralyzes the ferret. It doesn’t harm them, all ferret owners scruff their ferrets.
Nip training is hard. If you have a kit that bites it takes a lot of work to nip train it. Once a ferret is nip trained it will generally never bite again.
Ferrets sleep 16-20 hours a day. They are much more needy than bunnies are. When ferrets are out for playtime they will keep you on your toes. They like to swipe stuff and hide it. They don’t chew on things though.
Ferrets are obligate carnivores so feeding them premium food is a must. Much like rabbit food…most of the commercial ferret food available is crap.
The life span of a ferret is 7-9 years, if he’s healthy. They require rabies shots and canine distemper shots every year. I personally don’t get mine vaccinated any more because I have senior ferrets and at this point it could do them more harm than good. They don’t go outside and they aren’t registered so this is a personal call for me. I don’t advocate not vaccinating ferrets and mine have had regular vacs up until 2 years ago. my ferrets are not 5, 7 and 8 years old.
Are you getting one?
