At the forefront of microchip technology and pet recovery services

Leave the hassle behind with an advanced range of innovative microchips at the forefront of animal identification and monitoring. Designed to help you care for animals with the minimum of fuss.

More Than Just Identification.

HomeAgain® is a range of high-quality bio-glass identification microchips for cats, dogs and horses that are used to identify the animal, and their owner. Sitting within the HomeAgain microchip range is HomeAgain Thermochip®, a new generation of identification microchips that incorporate an integrated temperature biosensor. This enables an animal's temperature and identification number to be read simultaneously via a non-invasive stress-free method.
