Probably the best litter in the world
I just switched to this and I love it. Most importantly, my cats love it. On switching I had one tray with the old, and one tray with golden gray master. My kitten was straight in it, getting all excited, and my old girl refused to use her old litter. So we went straight onto it, and for some reason, cats absolutely love it, perhaps because it is very fine and comfortable.
For me, its great, and this is a bit of a confession, but... I enjoy cleaning out the litter trays now! I look forward to it, morning and night, because the poo and wee clump beautifully. Once scooped out, the litter is beautifully clean and looked like its never been used.
Its not as messy as larger grained litter and doesn't seem to get on the carpet too much, but my kitten gets really overexcited when in the tray, digging and weeing and playing. he even tries to go to bed in his tray!
I think a big last will last 2 or 3 weeks for 2 litter trays and it is well worth the money. Ok, its a bit stinky when they do a poo but that's cats for you. You can easily scoop it out as soon as it is done, and your house smells nice again.
I'd never use anything else, now I've found it.
