【Material Matters】A bowl is just a bowl, right? Sadly, that's not the case. Most pet food bowls are made from stainless steel, plastic, ceramic. Plastic is the worst option which contain chemicals that could disrupt an animals hormonal balance. Apart from that, plastic accumulates deep scratches that harbor insanitary things and can be hard to clean. Ceramic is heavier and far less durable. One drop or bang can chip, crack, or shatter your ceramic bowl, making it no longer safe for use 【Human Grade & Food Safe】Veterinarians recommend stainless steel, because of its highest safety over plastic or ceramic bowls. Podinor Pet dishes are made in a facility that typically makes human grade products for the healthcare and food industries. After manufacture, each batch of bowls is tested for lead, mercury, and cadmium by an independent lab. These bowls are so safe that they're fit for human use, too! 【Large Capacity】Enough capacity lasts all day without a refill and to make sure your dog doesn't drink from toilet.
