The problem I am having is that the little pegs that keep the tubs from coming out tend to fascinate my darn cat. She is always knocking them out.

My fear is eventually she will also get the tub out too.

How can I secure the tubs. What else could I put in those peg holes.

I currently have strips of Velcro taping my tubs shut.

Any suggestions? Unfortunately I can't lock the cat out of the room the rack is in.
