I do not recommend
After 4 years of using Everclean, I decided to try Tigerino (because of the good and very good reviews!). I was disappointed. Even though I mixed the two brands in equal parts (I didn’t know how the cats would react), in a freshly cleaned litter box, after less than half a day, the litter smelled terrible. Not to mention it was stuck really badly to the tray. I have 2 cats who use a single, huge litter box, and with Everclean I never had any problems. Today, after 2 days of use, I’m going to throw all the litter away.
