Energy level visualized. See the signs before they become issues

Behavior reflects daily energy level and loss of energy is a common reason for vet visits. Catlog detects signs of discomfort such as decreased appetite and activity, to help decide when to see a vet.

Catlog can detect:

Lack of energy


*More detectable issues will be added in future updates.

*Enegy Level is calculated by Catlog's original algorithm. It can be used as an indicator for cat's health management

Frequently Asked Questions

From what age can a cat wear it?

We recommend Catlog to be worn from about 6 months of age, when the cat is in its junior years and approaching the size of an adult cat. Since each cat has a different build and neck size, please check the size of your cat's neck in advance. You can keep an eye on your cat while he/she gradually gets used to wearing it.

Can it be worn by pets other than cats?

As the saying goes, "Cats are not little dogs." Dogs and cats are completely different animals, and each animal has its own species-specific ecology and personality. Catlog is a product developed with only cats in mind. We hope you understand that Catlog will not work properly if it is attached to animals other than cats. (Our staff loves animals in general nonetheless.)

Can I watch my cat's activities, no matter where he/she is, in any kind of house?

Your cat's activity can be recorded only when there is a stable wireless network environment in the 2.4GHz band and the BLE connection between Catlog Pendant and Catlog Home is uninterrupted. The connection range may vary depending on the layout of your home, the number of floors, whether doors are opened or closed, how furniture is set up, the cat's posture, and other factors. If you are considering using the system in an area that cannot be covered by just one Catlog Home, we recommend purchasing and installing additional Catlog Home devices.

How often should I recharge the battery?

Although it depends on the usage, the battery should last for about a week. Charging time is approximately 60 to 90 minutes.

Is there a warranty period?

This product comes with a one-year warranty from the time of shipment. However, the warranty does not cover intentional damage.
