Doesn't sound too promising. Tbh, it's not easy to get hold of as few places seem to sell it, so I might just try the worlds best. Tracking is a problem, but it's not the main issue. If I like a litter, I will put up with having to hoover more often. The oko is just not good enough re odour control. At least WB comes in extra strength if the normal one isn't good enough! And I can get it from PAH and Jollyes. Probably not the cheapest places, but useful if you run out and need to get some quick. Don't think there's anywhere I can get chick crumbs from around here.
