Okie doke... so I just picked up Bonnie and Clyde and they were in tiny containers. So I went to Walmart the other day and picked up some bigger tubs. They are 26 1/5" long x 16" wide x 6 3/4" tall. Now I thought they were big enough, however, I picked up some of the small litter pans for hides. The tubs are barely long enough to fit two litter pans, forget about a water dish. What size am I supposed to go up to for these guys? Did I get the wrong litter pans or the wrong tubs?
