I wouldn't worry about the eating of the litter unless they are really snarfing it down, kittens like human toddlers just seem to have to "taste" everything. When they discover it doesn't taste good they usually don't continue.
Agreed.
I have raised hundreds of foster kittens and I never worry if they eat a bit of litter. Most of them do sample a littleof it when first introduced to any litter.
At the age of 4 weeks, I use either non-clumping clay or newspaper pellets.
Once they are about 6 -7 weeks old (usually by 6 weeks), I switch to clumping clay litter. As discussed on my Litter Box page linked below, I strongly feel that pelleted litters (newspaper or pine pellets) are very unsanitary. Using a non-clumping litter does not all you to completely 'flush the cat's toilet'....ie....there is just no way that you can remove all of the urine and feces. Plus, those litter turn to either sawdust or wet newspaper and the only way that they got to that form is from being soaked in urine and I am not going to ask my cats to walk in sawdust/newspaper that has been soaked in urine. Plus, I don't want urine-soaked sawdust tracked around my house.
I deal with a lot of inappropriate elimination issues and so often it is due to the human using a pelleted litter or a non-clumping clay litter. I have lost count of the numbers of cats that have started using the litter box again once a normal substrate that they can dig and bury their waste in - *and* that can be thoroughly cleaned because it clumps - is used again.
I would get the kittens on a clumping litter at least by the time they are 7-8 weeks old....since, again, clumping litters are the only way to completely 'flush the cat's toilet' ....ie....remove ALL of the urine and feces.
If you don't want to use a clay litter, World's Best Cat Litter also clumps but it is harder on the lungs since it is very dusty and hyperallergenic.
So for now, either use the non-clumping clay or try the Yesterday's News pellets but get them on a clumping litter asap.
