Outreach to Pets In Need will host a free HomeAgain microchip clinic from 4 to 6 p.m. on Saturday, May 18, at New Canaan Mounted Troop, 22 Carter St.
OPIN already has given away 314 free microchips since April 2012.
Local pet owners can have dogs and cats microchipped at no cost. It includes lifetime registration of the pet. Cats must be in carriers and dogs on leashes. No appointment is needed.
One in three pets will get lost. Without identification, 90 percent of them will not return home. A microchip is the only permanent form of identification that cannot be altered or removed. The procedure is simple and similar to a routine shot. A chip, about the size of a grain of rice, is implanted by a veterinarian between the pet's shoulder blades just below the skin. The process takes a few seconds and no anesthetic is required.
When a pet is found, a scanner is used to detect the presence of a microchip. Each chip has a unique number that corresponds with a database like HomeAgain, which contacts the owner.
