Child Proof Drawers My Kittens Vs. My Kitchen Counter? Climbers?

My kittens Vs. My Kitchen Counter? Climbers? - child proof drawers

Well, not really knowing what to do and now I'm annoyed because I started writing I had to do one of my cats, since 4 Counter-times available. K is now five years.

Anyway, we have a series of four drawers, which led to the kitchen sink. My cats have learned to open it. (They put their feet on the tray, then slide open.)

He also discovered how to use these boxes as stairs. (Yay.)

I live on a military post, so I do not know if I can test these tabs for young children get to stop freaking the drawer. Is there anything I can do?
