Just thought I'd pop in & give a poopie update...
I give them THK for breakfast & kibble for dinner now & it's the same result! I am stumped.

I've found out that Turbo is also beef intolerant! He threw up after eating Stella & Chewy's Freeze-dried Beef patty (got a sample). I thought it was the pumpkin seeds (4got that was in there!), but he also threw up after eating NV raw Beef medallions. He does fine w/chicken, so sticking w/that.
Mimi & Turbo seem to do very well on premade raw, so I am thinking of giving them only that for dinner, no more kibble for them. Thank You for reading my ramblings & helping me trying to figure out their poopie business! lolll
