Hi there... I thought I would seek some advice from the resident food experts here. I am interested in finding a good premium to mid-range dry food with the fewest grains to feed to all three of my cats which range in age, 11 years, 6 years and 4 months. I have them on TOTW right now but I am not sure it is agreeing with them or not. The clumps I am scooping out of the older two's litter box seem really large and the kitten is pretty much having stinky soft serve, yuk! Thanks for any advice you can give...
