True to its name, PetsForPets is a pet feeder specialized for cats, dogs and birds. It is composed of waste PET bottles integrated into the main plastic structure. Serving as a sustainable simple food reservoir and a water tank depending simply on Torricelli’s law , waste bottles of 5 Lt and a 1,5 Lt are positioned upside down to complete the product. In this manner, pet-owners do not have to worry about their animals when it is inevitable to leave them at home during the long-journeys. It is favorable owing to the opportunity ensuring to feed pets at the same time, as the channel inside forms a waterway for the birds. PetsForPets is convenient not only for pets, but also for stray animals living together in the neighborhood, thanks to the easily combined products formed up to a four-pieced sets of each. Optionally, this set can be hanged by the help of a rope passing through the connection points which are designed consciously.
