Hello, I'm new here and have two 13 week old kittens. At the moment they are using wood pellet litter (as they did with their breeders) with small kitten litter trays. They are making quite a mess what with kicking the litter over the sides so time to buy new bigger ones I think. So please help me decide whether or not to stick with the wood pellets. I don't understand the pros and cons of each and was wondering what was the most popular. One of my kittens is scraping all the wood pellets aside when doing a poo (so it goes straight on the plastic). For this reason I am wondering if the clumping type would be better, but I have never used it. Sorry to ramble. I'd be grateful for any advice.
