I’ve switched to ökocat, which is basically just wood pellets. I think it’s made in the USA, but I much prefer it to traditional clay. I’ve seen some people on YouTube demonstrating how to use wood pellets from a farm/feed store, and it ends up being dirt cheap. The main difference I think is that okocat clumps, while the sawdust type wood pellets disintegrate when wet, requiring a slightly different cleaning approach (but still easy). Might be worth looking into wood-based litter since Canada has lots of trees.
