Hello, my 8yr old male cat is picky in his litter so I've always stayed with Fresh Step. However since he's been a diabetic now for the past 10 months he's been tracking his poops all over the house. Never use to before. So I looked back at past posts and I read some good valid points. I'm gonna try gradually like switching hard to wet food so Rupert will still use the litter box. Dr. Elseys. Gonna mix some in his litter he likes until he's completely using different litter! Good luck on getting the info to best help you decide.
