OK, so my cats are in a safe room out at the farm... There is regular garbage pickup, but there's also horse manure waiting to be spread. DW thinks the used kitty litter can go in with the horse poop. This bothers me a little--I don't know a thing about what's in the kitty litter. (Besides cat poo!) I was thinking about this... I know they make all kinds of organic kitty litter--but I don't feel like paying a ton for wheat or cracked corn or pine pellets... Does anyone know if the horse pellet bedding is anything like the kitty litter pine pellet litter? They kind of look similiar. I'm curious to just try it in one of their litterboxes... will it fluff up with kitty use? Wonder what the cats will think of that?
