Here's why:
* Size difference: Ferrets are typically much larger than skinny pigs.
* Body shape: Ferrets have a more elongated and slender body shape than skinny pigs.
* Clothing design: Ferret clothes are designed to fit their specific body shape and size.
Trying to force a skinny pig into ferret clothes could be dangerous and uncomfortable for the animal. It's important to find clothes specifically made for skinny pigs or use other methods to keep them warm, such as blankets or sweaters.
