Bliss Basic Horse Bedding?

Has anyone used this for guinea pig hutches or rabbit litter trays?

I've been looking online, and the pet shop where I get my bunnies food from sells this stuff. It's supposed to be dust free, really absorbent and soft - It's quite cheap for a massive bag too.

I think it's made from really finely chopped straw or hay.

(P.S. I hope this belongs here - I guess it is to do with housing lol)

if it is the originak then i use itfor my buns litter trays and ave ad no problems
