Our new shelter kitty (8months) has the stinkiest poop. He clears the house when he uses the litter box. I have considered parasites and will get him re-checked, but for now am trying different foods. Wellness chicken made a huge difference in the smell (but not the consistency, still runny), but kitty doesn't really like it. Other brands we've tried like Nutro and Blue Buffalo cause major stinkies. Any other suggestions of a food to try that might have good results for him. We have a Petsmart and PetCo locally. Once I find something that works, I will order it online.
