i have 2 kittens around 6 months old. their poop really stinks. i put arm and hammer deodorizer when i scoop it out (which is everyday) and have an automatic air freshener near the litter boxes. my last cat that i also had when she was a kitten, also had the same problem, but i believe it was more pee smell. anyways, is it typical for kittens litter boxes to smell worse than adult cats?
