Says Planet Green: “Scoop up your doggie doo in biodegradable poop bags so your buddy’s No. 2 isn’t immortalized in a plastic bag, while deep-sixed in a landfill somewhere for hundreds of years.” And for cats, Planet Green recommends this: “Owners should avoid clumping clay litter at all costs. Not only is clay strip-mined (bad for the planet), but the clay sediment is also permeated with carcinogenic silica dust that can coat little kitty lungs (bad for the cat).

There are lots of resources on the web to help you green up your pet. One, Planet Green, says to keep your cat inside, and your dog on a leash.

For a safer flea and tick repellent, try scattering pine needles, fennel, rue or rosemary on your pet’s bed. Or feed your pet brewer’s yeast, vitamin B or garlic tablets.
