What is a very SMALL skunk called?

There isn't a specific name for a small skunk. Skunks are generally categorized by their species, such as:

* Eastern Spotted Skunk: This is a smaller species of skunk, but it's still called an Eastern Spotted Skunk, not a "baby skunk" or something similar.

* Striped Skunk: This is a larger species of skunk, but even young ones are still called Striped Skunks.

If you're talking about a baby skunk, the term "kit" is commonly used.

So, if you're referring to a young skunk, you could call it a "kit." If you're talking about a small species of skunk, you would simply refer to it by its species name.
