Just a heads up for anyone who uses a Litter Locker: Canadian Tire on Barton and Kenilworth is selling Pad Locker Refills (which also fit Litter Locker I) for $1.43 on clearance. If you use them you know they cost like $7.50 normally so this is a great deal. I went this afternoon and got 8 of them and there were still plenty left.
