I can't do that, but have you tried giving him/her coconut meal? They stink less! Just one tablespoon in their food every day and you're set. And it's really cheap, too, because you get the stuff for horses, which is priced to be fed in horse quantities.
Don't be mean about my horses' nicknames, Monty gets called boofhead because his head is ENORMOUS! [seriously... Magic's stuff is too small for his head and his stuff is too big for Magic's head, and Magic is at least a hand taller than him!]
