I ended up getting an $8 plastic container at Petsmart because my cat would get into the cabinet and shred his food bag. It was the best cat investment I've made.

I think all cats think they are malnourished - even 20 lb ones

Especially when they roll over when they're trying to get food attention: "Oh look at my tummy, it's so empty! Fill it up! *jello wave as they plop down*"
