Thanks for the tip. Unfortunately the closest tractor supply store is actually farther away from me than any Petco. I did end up getting the Harmony Hills Chicken and Rice formula. I began the switch the other day and even though they aren’t getting more than a handful combined with their old food, so far its been good. No complaints, issues, upset tummys which is good. I’m sure the real test is when the switch is complete and its like week 2 of being on the new food full time, but I’ll deal with that when it comes!!
