I've just tried these for the first time. Filled just one litter tray with a sample bag of chick crumbs and the rest with my normal Worlds Best. Cats seem to like the chick crumbs and I think they are great. They don't go powdery after a while like the Worlds Best can. The smell is just a wheaty type and they clump really solidly so easy to remove. I will defo be changing to Chick crumbs from now on. Just need to find a good supplier, mine are a bit expensive still down here it seems, £13 for 25kgs, am looking for a site online that will deliver that is cheaper. If anyone knows of anywhere, please let me into your secret.
Still better than £36.00 for 15kg of Worlds Best though.
Also, kittens seem to get on with them and no one has tried eating it or anything.
