I am on my first day of Cats Bests and they are all LOVING it!! it clumps well , doesnt smell and although it has tracked a bit its not reached out of the conservatory yet! AND it oesnt weld itself to the bottom of the trays! 
Yes thats a big plus compared to clay clumping litters isnt it?
what made you stop using crumb Gillian?
It was when Gwynnie was so ill last year and had high coronavirus titres - I switched to a cat litter that actually kills the coronavirus, Everclean (its one of the ones listed on Dr Addie's site). Everclean's a really good litter, similar to Sainsbury's ultra clumping, but even better I'd say (more expensive though). Also I found that the chick crumbs I was using were medicated
(and possibly may have had something to do with her paralysis). I'm not so worried about corona now but decided to check out different litters (what fun LOL!) - and so here I am with Cats Best Gold - for now.........
