The pot o' gold at the end of the rainbow is at Harris County Animal Shelter! Celebrate St. PAWtrick's day by changing the luck of one of our deserving pups or kitties. On Sunday 3/17, pets designated with a shamrock lucky charm (or a green kennel card) are FREE to adopt—there are several. Adoption fee for all others is just $17! Every adoption includes their spay or neuter, age appropriate vaccines, 1-year license and a microchip.
