Not a Good Idea
Ferrets have different body shapes than dogs—long and slender versus compact. Dog clothes won't fit properly and could be restrictive or dangerous.
Ferrets have sensitive skin, are escape artists, and don't need clothes for warmth thanks to their thick coats.
Alternatives
Consider ferret-specific sweaters or custom-made clothing designed for a ferret's unique shape.
Always prioritize your ferret's safety and comfort. Consult a veterinarian or ferret expert if unsure.
