Instead of frequently cleaning out your pet's dishes, Bamboo's Feed and Toss bowl system includes disposable liners for food and water. Each bowl comes with two clear plastic liners and a recommendation to use one liner per week for water or dry food and two liners per week for wet food. The product eliminates the risk of mixing household sponges, unsafe cleansers, or spreading germs to family members when cleaning pet's dishes. Now, when traveling I can see the benefit of a product like this, however, I think I do a pretty good job of cleaning North's dishes on my own at home. What's your take on this product?
