Choose a litter that’s safe for ferrets. These include:
Recycled newspaper pellets
Alfalfa pellets
Denatured wood litter pellets
Never use litter made from cedar or pine wood shavings. They contain essential oils, which are harmful to ferrets. Also, avoid the following types of cat litter:
Silica-based crystal cat litter can cause respiratory issues in ferrets.
Clay litter can get into ferrets’ eyes and get stuck on their paws. It also contains silica.
Sand-based cat litter can clog ferrets’ sinuses if they tunnel in it.
