Do I wash my ferret again?

Ferrets have scent glands and always stink. There is a special ferret deodorant you can buy for them to use in between baths. Your local pet store should carry it. If you are using a good pet shampoo it should be okay to bath him just make sure that you thoroughly rinse him. You could also get a damp towel with no soap and wipe him off. I had 2 ferrets when i was younger. They are sweet pets. Good luck.
