Dog/Cat treat dispenser

A dispenser for small dog/cat dry food to keep your pet amused. Designed it originally for my daughter's puppy, but works well with our cocker spaniel as well.
You put the treats in the open end where they sit in the centre cavity. When your pet rolls it along the floor, the treats are guided through a helix at either end and pop out on the floor for them to eat.
Would only recommend using it under supervision as initially our spaniel thought that it may be easier to take it out onto the lawn
