A simple Pet tag or the whole pet identification system is so important according to a research conducted, and 80 percent of the pet owners agreed with the system. The importance of the pet tag is that it contains the name of the pet, name of the owner and contact number of the owner. Even when a lost pet found a shelter, it typically has slim chance of being reunited with the real owner, unless it is wearing pet tag.
Some people steal cats and dog for sale to research laboratories or to a black market pet dealer, your pet is safer if it wears some sort of identification. While these precautions may not prevent your pet from being stolen or lost, an identification which is permanent may enhance its chances of being recovered. Many laboratories do not buy a tattooed animal and most pet shelters look for tattoos and 
other forms of pet ID. Here are some pet identification system for cats and dogs:
- Tattooing. Using a topical anesthesia, tattooing becomes a painless procedure provided by many veterinarians, it involves inking the Social Security Number of the owner or other special code on the rear part of the inner thigh. For best results, register the tattoo with a pet protection service nationwide that has a 24-hour hot line for tracking the number and finding the owner, no matter where the pet is found. An appropriate registry can be recommended by the veterinarian who does the tattooing.
- Collars and pet tag. These Identification tools can be lost or removed, but still, they are better than nothing at all. Some collars and tags are given by a government institution who gives a free rabies vaccine, and some owners put a pet’s name along with the pet’s owner contact number.
- Microchips. Animal shelters around the world are using microchip technology to reunite owners with their lost pets. To be able to use such ID system, a tiny chip is injected between the pet’s shoulder blades by a veterinarian. The chip reflects radio waves emitted by a hand-help scanner, which reads the chip’s code number. The veterinarian registers the code number as a virtual pet tag in a computer database for tracking.
Adopting this pet identification for cats and dogs will give a chance for your lost pet to reunite with you, even if you lost your pet when they are still pups or kittens.
