I tried a new food for Frank.

It's freeze dried and smells terrible (so I figured Frank would love it), but also has a resealable and small bag and should last a little longer than the big bag of regular dried food.
Frank did really like it, but even though I soaked it, the pieces were a little big (I broke a few of the larger ones) and kind of dry inside. I plan to crush or cut into smaller pieces and soak longer and I think it will be a success.
At first he didn't know what to make of chewing them!
