PetSmart should have the lava ledges in like the small animal section. Sometimes they are hung in the aisle with the hay and wood sticks and all that but are on the opposite side where the bunny and rat harness and stuff like that is. Lava bites they don't have but I know PetCo has them. My chins LOVE :throw: the lava bites. They demolish them the way I would a piece of chocolate cake...haha. The lava ledges I bought also and mine did chew on them but after awhile it just became another ledge for them without having sustained much damage. I don't know if the size just daunted them or if it lost flavor or something but they still love lava bites best.
