Our cat, Loco, shot out the door or our house and into the night when someone walked in. 9 days later a family about three miles north of our home saw him in their bushes. His collar was gone so they started feeding/watering him. They took him to a vet to check for a microchip. The vet’s office contacted me and I dropped everything to go pick him up, bawling the whole way. If it weren’t for his microchip, Loco would now be in the care of another family. His collar was lost, so there was no way to contact us other than for the chip to be scanned. I’m SO HAPPY I invested in this chip!
