Don't worry about the safety of your pets or the environment – our silicone pet products are made of high-quality food-grade silicone and, therefore, are safe for your pets and the environment. Silicone, on the other hand, is a sustainable alternative to ordinary plastic since it is long-lasting and can endure degradation. While we do our best not to manufacture too many un-recyclable silicone products, we do provide some instructions, as not all silicone products are recyclable, and we need to take care of our planet.
