I have been checking out some of the magazines around here. I strongly recommend Bark for the doggie pictures and the tasty cards that fall out of it. These cards make a wonderful mess and can be eaten if you chew them enough. I suggest washing them down with some chilled water.
The New Yorker, on the other paw, has more substance. Hardly any pictures of doggies or even humans. But the pages are very tasty. They are a little slippery and shred nicely. If you are extremely hungry, the cover makes a good snack. But for making confetti to decorate the carpet—it’s my favorite.
We sometimes have newspapers lying around too. They are very shredible in a pinch. But for a truly satisfying experience, I recommend magazines!
