When we first got our kitten from the humane society they gave us a bag of Science Diet Kitten for him. Rather than waste it I continued to feed it and started adding in Innova Evo probably about 2 weeks ago. He took to it quickly and the Science Diet ran out, so he is purely on the Evo now. I didn't notice much of an odor when he was on just the science diet, but now on the evo his poops stink up an entire floor on the house. He just pooped in the ferrets upstairs litter box, and I had to completely empty the box, open windows, and spray air freshener to help with the smell. Is this just an adjustment thing with the food switch, or is this not going to get any better? Evo is a good food, but I can't live with this smell forever. If this is just what his poops will smell like on Evo I'll have to find him a different food.
