Yes cats can be food stealers. When Alani & Blaze were kittens they would get into all of my lower kitchen and hall bathroom cabinets. They would then pull things out and destroy them. I had to install child safety locks on all of the doors. Sometimes they're still able to pull things out if they can reach them. I then tell them that they must've been fishing again. Alani still loves to destroy any plastic or paper product so I have to be careful not to leave anything out. I can't even put the kitchen garbage can in the kitchen any more because they get into it or knock it over. It's now back in my bedroom where they aren't allowed. Sometimes I think I have a bunch of dogs not cats. I do watch my food too but I also have to watch my water or Rory or Sky will start drinking from my glass or even knock it over.
