HSP ... we've had good results with the metal step-on lidded trash cans. Even if your poo figures out how to step on the pedal to open the lid, he'll likely get a pop to the head once he lets go
. I've also found them from small to large quite inexpensively at HomeGoods, TJMaxx, KMart and Target. They are great in the kitchen and bathroom. The cayenne pepper could potentially cause an allergic reaction or damage to the fragile membranes of the nose ... ouch ! Hope you find a sure proof solution. Keep us updated.
