Nails Ferrets nails need to be trimmed regularly. If they are allowed to grow too long, they can split, or be torn, resulting in infection. Put some on the ferrets tummy. He'll lick it off, giving you time to trim his nails just below the pink areas. Use cat nail trimmers or human nail clippers.
Teeth Dry food is recommended over soft food, it helps keep the teeth clean.
You can brush your ferret's teeth with a soft bristle toothbrush and pet toothpaste. If you see dark plaque, especially on the back molars, a vet should remove it. Bacteria in the plaque can cause kidney problems.
