I'm just so glad to read Roxie is doing better and getting livelier! It is SO good when they start to get better!
What were her final diagnoses?
With my Jilly who was tiny, if the store was out of her Science Diet for Sensitive Stomach Small Bites and I had to buy regular, I would throw a bunch in a storage bag, zip it closed and use the rubber mallet to crack it up, empty it into her bowl. That food was THE ONLY food her GI system could tolerate so I had to make it work and the food processor and blender usually powdered too much of it. A few whacks of the mallet and you are done without much powdering.
Best of wish that Roxie keeps getting better and better from now on. Bet mommy is breathing a lot deeper these days.
