You don't need a handle to paint with a ferret, they are self-attaching! (Don't wear a glove - you big sissy).
They are best used with RED paint as the blood won't discolour it.
If you are using ferrets in low brightness and out of direct sunlight, an AAA battery with a high brightness LED attached can be inserted into any suitable orifice (a resistor is not required as the ferret does that). This, not only aids the drying process, but also enhances the self-attachment properties.
Badgers are useless for detail work and should only be used to paint fences - after which they usually give up their life of crime! (No, NOT the badgers...)
