Double bag and dispose of your pet waste and kitty litter in the garbage. Landfills are designed to handle pet waste safely. 

Yards, trails, streets, parks, toilets, and compost piles are not. Burying or composting pet waste allows harmful organisms into groundwater. Harmful organisms can be transmitted from dog waste to children. Some can persist for weeks in your yard, waiting for a host. ​

Remember to take a bag with you on walks, or use the dog waste stations in common areas. At home, daily pick up is best.
