Honest Kitchen and increased POOP

FYI - I rotate between Addiction and THK and don't have the poop issue. BUT, that's because on the THK I give about 1/2 the recommended feeding amount. Boyz had been getting 1/4 cup Addiction + 1/4 cup water and are happy as clams. When I added THK in as an option and was giving them nearly 1/2 c + 1/2 c (as per box) I got way too much poop - which means way too much food (usually they're on Primal raw so very little poop is our norm). They've all been on either THK or Addiction for at least 6 months and I've seen no weight loss / hunger issues. Vince actually always gets THK (he can't do venison and Addiction has 3 venison options so rather than screw up I just don't give it to him) and even on 1/2 the box guidelines he's maintaining his weight just fine. FYI all mine weigh 21 lbs. give or take 1/2 pound.

I switched Angus to Thrive and his poops are now down to two per day, with no bits of undigested food. Think I'll keep Cal on the Force (his allergies are so much better) and Angus will stick with Thrive for now.
Certainly do appreciate all the comments and advice. You guys are great! Who else would listen to long conversations about poop??
