yeah you can get a little doodad to connect a big refillable canister that you can get refilled locally. you’ve been soending way too much if you buy any comoany’s proprietary consumable accesories.

recently bought a petsafe scoopfree litter box on clearance which has reallu expensice refills because the bottom of the trau is cardboard. i bought a third party stainless steel tray. entirely undermined that business model.
