When I was trying to teach Blu how to use it she got frustrated screamed on it,nearly bite me and then push it down from coffee table and ate treats from floorluckily Bluey figured on her own how to open drawers and Blu just started to mimic her at some point@dido .
Have you seen the one made by Trixie
Little wooden box with three drawers and a string on the front of each one?
I do the "find the lady" trick not every drawer has a treat and also pack them with shredded paper.
