Today, regulations and laws governing the keeping of animals, countries, communities and municipalities are becoming more stringent and require a method of identification for animals varies according to current regulations.
Undoubtedly and, although this may require another operation, the identification system is needed to protect animals against possible loss, theft or abandonment.

The cat is an animal that gradually falls within the framework of these laws and it must be identified and in many areas. Before the identification should seek advice about which is the method that our region requires us either veterinary centers or the Town Hall.

The plate.
It is the most rudimentary and less reliable. Is to hang a plaque on the collar, bearing the address of the animal, who are its owners and a contact telephone number.
This board is not at all sure in the case of cats, this collar can be easily removed either by choice or get caught on a branch.

The tattoo.
This is a procedure implemented in various countries such as France. It consists of tattooing in the animal's ear with a code which is entered in a database that contains the name, address and telephone number of landlord. When a stray animal is captured, we proceed to identification by tattoo code and located the owner. The tattoo is done with local anesthesia and a device that carries the code ready, it is painless but annoying.

The microchip.
This is the most revolutionary and safer animal identification, it can only be removed by surgical intervention and its implementation is fast i almost painless.
The microchip is a small capsule containing a tiny computer circuit corresponding to a specific number. Passing a reader goes above the number printed on the screen reader. Obviously this result is contrasted with a database where it appears the owner. The microchip is applied with a needle that injected subcutaneously, is then wrapped and fixed by a protein capsule that creates the animal to its surroundings, thus, has little mobility and are easily located with the reader. It also has the advantage that can not be altered as might occur in a tattoo.
The microchip is safe for animal and not cause damage or allergic reaction.
Today is the identification system is being implemented worldwide. Just go to the vet, implanting the animal and complete the form to the database which will send the same vet where appropriate, either official veterinary school or agency to manage it.

We emphasize the usefulness of having companion animals identified and it is not unusual that may be lost even living in a flat. It is the first case of a cat falling from a balcony and is recovered by their owners when the vet as identified in the consultation. Otherwise it is very difficult to get a pet unless someone recognizes it, and this usually does not happen.
