Oasis was established in the early 1960s in the San Francisco Bay Area by mechanical engineers and scientists who were developing sanitary water dispensers for use in laboratory and medical research animal cages. The group of animals that needed reliable, clean water delivery was very diverse and included mice, rabbits, birds, dogs and chimpanzees. The unique waterers that Oasis invented replaced the old, leaking glass "sipper tubes" and were so succesful that they were introduced to the pet trade in 1964. They were an instant success and Oasis has continued to be the worlds leader in sanitary water dispensers, including new designs and product innovations for all types of pet animals. Oasis products are designed to provide your small pet with the very best feeding experience possible. Their no leak, veratile bottles are the perfect solution for keeping your pet hydrated and happy.
