To use these N - Bone ferret treats, simply give them to your ferret as a reward during training or just for a special snack. You can offer one or two treats at a time. As for storage, keep them in a cool, dry place to maintain their freshness. When it comes to your ferret's diet, these treats should be a supplement, not the main part. So don't overfeed your ferret with them. And always make sure your ferret has access to fresh water. If your ferret has any specific health conditions, it's a good idea to consult your vet before giving these treats.
