True to its name, Pets For Pets is a pet feeder specialized for cats, dogs and birds, composed of waste PET bottles integrated to the main plastic structure. Serving as a sustainable simple food reservoir and a water tank depending on simply 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 4-pieced sets of each. Optionally, this set can be hanged in streets such as to light poles to provide a feeding station.
