Has anyone on NVI Lamb L.I.T. notice frequuent poops? When Bruin & Lilly were on the Turkey/Duck, they would poop twice a day (like clock work), I switched to Lamb and now for the past 2 weeks they're pooping EVERYTIME they go outside to pee. They're solid, not runny...but they're smaller "balls" of poop. Why do you think that is? And a few times I got the idea that Bruin was having a little trouble pooping. Do you think it's because there's less "junk" in the food to poop out?(it being LIT and all, not that the nvi turkey was junk)
