Means for containing and handling pet litter, wherein a reusable, collapsible frame assembly is used cooperatively with a flexible trash bag to provide a structure for enclosing a litter container while in use, allowing the pet caregiver to dispose of the entire litter container without touching it. The reusable, collapsible frame assembly is designed to support the trash bag while in use, and to be partially or completely compressed for removal so that the litter, bag, and optionally the litter container can be disposed of together without requiring the animal caregiver to touch the contents.
