@mom2jel try wood pellet horse bedding. $6-$7 for 40 lbs at Tractor Supply. Solids go down the toilet and the sawdust is much lighter than clay if you don’t have a way to compost it.
Sawdust takes a long time to compost unless you have a lot of carbon matter to mix in but clay doesn’t compost at all. I take our sawdust to our “stump dump” where is gets bulldozed with leaves, trees, garden waste, etc.
I got the A&H since its a MM but it’s headed to my next yard sale.
