• Pet Waste that is left uncollected degrades water quality. With an estimated 134,000 dogs and 154,000 cats in Lee County, this results in a lot of waste that washes into our waterways increasing bacteria and nutrients. Join us in our Do your Duty campaign and pick up the waste! To learn more visit DoYourDuty.org and stop the Slime Monster.
