I was at a fiber festival recently, and saw that one of the vendors used some kind of pellets (equine pellets was on the bag) for the rabbit trays. I asked about them and they said they got them at Tractor Supply. I went to TS today and asked and they have two kinds: one is a wood based pellet and the other is a corn based product (don't know if it is a pellet as the bag was opaque). Do any of you use pellets, and if so what kind? Are they more effective in keeping odors to a minimum than shavings? Also, I will use the tray material in the vegetable garden later. I thought I might use the pellets if someone has had a better experience with them than the shavings, assuming it is also okay to put in the garden. Please relate your experience using them and which kind you use. Thank you.
