Yes, SHE discovered it... NOT ME! Dont ask, just suffice it to say, Mouse has caused my place to stink like vinegar... and she now has HIVES all over! If it's not one thing, it's another! I wonder how much hair she'll lose from THIS one! So now that's metal (stainless steel is included in this) and Vinegar... Can Mouse get any weirder??? Even her allergies are weird!
