^^ been there. had to get clip locks for my fridge.. may have to do it again, Jack is back to raiding it now that her realized the new fridge doesn't lock...My cats are like that too. I have had to buy childproof locks and put on EVERYTHING
Just go to home Depot or Walmart and buy alot !
I also had to get doorknob covers for awhile because he can turn the knobs and let himself out and the chain lock didn't prevent him from squeezing out.. and he HATES going outside.. he just opened the doors for the rest
