You maybe considering going "green" if you have not already done it. But did you know that pets like cats and dogs often leave a surprisignly massive toll on the environment? The estimate annual cat and dog waste produced is about 10 million tons, jikes! Unbagged excrement can contaminate groundwater and soil with disease-carrying bacteria and parasite and bagged waste stagnates in landfills for years to come. Pets are also exposed to toxins through their food. A 2008 study showed that dogs and cats carry high toxic loads higher than those of their human owners. What do you do to take care of your pets and Mother Nature at the same time?
