## Background
BACKGROUND
The present invention relates to a display device for pets, and more particularly, to a display device for pets capable of providing various information on pets without being interrupted by movement of the pets.
As the number of family members decreases, more and more people live together with pets to avoid the monotony of everyday life, and the types of pets also increase.
