Rails model validation - validates_inclusion_of...

I have a string column in a table that can have a range of predefined values. It can also include a nil value. For ex: Dog, Cat, Bird, nil.

I want to write a validates_inclusion_of that checks to make sure all the values being entered fall within that predefined range. If, for ex, "Nasal Spray" is entered, it will throw an error.

What's the best way to do so?
