Feed your pet on-the-go with the Pop-Up Food & Water Bowl Set. The travel pet bowls' interlocking and collapsing design allows users to easily store the bowls together. Each set includes a carabiner that allows users to carry the pet bowl set hands free. A collapsed bowl can also double as a lid to conveniently store and carry dry dog food. Both the 10oz and 25oz bowl are made out of FDA food-safe silicone material.
