Microchipping your cat is an essential preventive measure that significantly increases the chances of being reunited with them if they get lost. By choosing the right microchip based on proper guidelines, you can ensure safe and effective management.

Cat Microchip Implantation is an Essential Preventive Measure to Increase the Chances of Recovery if Lost

Microchipping is a key preventive measure that significantly increases the chances of reuniting a lost cat with its owner. In reality, fewer than 2% of cats who become separated from their caregivers are returned home—a much lower rate than for dogs—primarily because there is no reliable way to identify them. Therefore, microchipping is recommended for all cats, whether they live strictly indoors or have outdoor access. The chip is implanted subcutaneously in the midline between the shoulder blades and can be read by universal scanners that detect all frequencies. Before implantation, it’s important to scan the entire body to check for any existing chips, and after implantation, verify that the identification number is read correctly. Keeping registration information up to date and having the chip checked during regular veterinary exams greatly contributes to your pet’s safety and your peace of mind.

5 Criteria for Choosing a Microchip

When choosing a microchip for your cat, prioritize safety, compatibility, and ease of management. It is essential to select a product that provides accurate information. Carefully evaluate each of the following criteria:

International Compatibility: Chips compliant with ISO 11784/11785 standards can be scanned worldwide.

Biocompatibility: The product is manufactured using biocompatible materials that minimize skin irritation.

Long-term Stability: The chip maintains consistent functionality, and its stability can be verified through regular scans.

Convenient Registration System: You can easily register and update information online.

Cat-Friendly Installation: The design ensures minimal pain during insertion and very few post-insertion side effects.

Caution: Visit a Veterinarian Immediately if Adverse Reactions Occur Within 2 Weeks After Implantation

If you notice any adverse reactions after microchip implantation, such as swelling, pain, ulcers, or high fever, consult your veterinarian immediately. These could be signs of infection or a foreign body reaction. If abnormal symptoms persist within two weeks after implantation, a visit to the clinic is essential. Observation is important for about an hour after implantation, and immediate action is necessary if early side effects occur.

5 Tips for Use After Microchip Implantation

Regular care is essential even after the microchip has been implanted. To safeguard your cat’s health and ensure the security of its information, please follow these important tips.

Regularly review registration details: Verify that your registration information is accurate once a year.

Perform scan checks: Have your veterinarian conduct periodic scan tests to confirm that the microchip is functioning properly.

Use the national pet registration system: Register your cat’s information in the official national pet registration database.

Keep detailed records: Note down the implantation date, the name of the clinic, and the microchip number.

Monitor your cat for behavioral changes: Closely observe the implantation site for any abnormalities. If you notice recurring swelling or signs of pain, seek veterinary care immediately.

Frequently Asked Questions

Does microchip implantation hurt?

Although there may be a brief moment of discomfort during insertion, most cats adapt quickly. The procedure is so straightforward that shaving the fur or applying antiseptic to the insertion site isn’t necessary, and it’s typically performed rapidly without anesthesia, so the pain is very short-lived.

Does the microchip move around inside a cat's body?

While most implants are located between the shoulder blades at the insertion site, they can occasionally migrate slightly to the back, flank, neck, or shoulder area. Therefore, during the scan, we systematically examine the entire body—starting from between the shoulder blades and extending to the back, flanks, neck, and shoulders—to accurately locate the implant.

Is it not possible to get a scan at a local veterinary clinic?

Using a universal scanner that reads multiple frequencies allows you to scan most microchips. However, some older devices may not be able to read all frequencies, so it's important to have your vet confirm that the chip is being read correctly with a universal scanner at the clinic.

Does a microchip affect a cat's health?

Microchips are a recommended form of permanent identification for cats of all lifestyles. However, abnormal reactions such as swelling or pain at the insertion site may occur after implantation, so it is best to consult your veterinarian if this happens.

Who can view the microchip information?

When scanned, the microchip reveals only the identification number stored within it. This number is then looked up in the registration system to retrieve the registered contact information and name. Personal data is protected, and access is restricted to authorized entities only.
