Thanks again, Kmaben. Gandalf was a Petsmart betta. I used to get all of my bunny supplies there, now just my cat litter &/or new litter pans. I have to admit of the local pet stores, Petsmart has the better heavier plastic litter pans. Thinking I will try the wood pellets for horse stalls to lower cost of litter. Maybe do a gradual switch with only a small amount of horse stall pellets mixed in with the more expensive paper cat litter to start.
