Ferrets really don’t need to be bathed often. This is because they do a great job at cleaning themselves. However, there are times when you may need to bathe them. I give my ferrets a bath about two times a year, once in the spring and once in the fall, normally around shedding season to help get any loose hairs off so they aren’t licking/eating them. Hairballs are known to cause blockages in ferrets. They don’t regurgitate them like cats. I bathe my ferrets using oatmeal in some form or another
