Well I finally gave in and started using the horse stall bedding for litter for my rabbits and now my local Tractor Supply is out of stock, doesn't know when they'll get more, and said it's a global problem with TS. I called around to find the wood stove pellets and a place down the road from me has them, but they are hardwood, not pine. Does it make a difference for the rabbit litter if it's not pine? The hardwoods they list on the ingredients are maple, oak, cherry, and ash.
