American Fancy Rat & Mouse Day is celebrated annually on November 12, promoting the appreciation of fancy rats and mice as pets. Unlike their wild counterparts, these domesticated rodents are known for their intelligence, affection, and suitability as companions, particularly for children. The American Fancy Rat and Mouse Association (A.F.R.M.A.), founded in 1983, plays a significant role in this celebration by educating the public about the positive qualities of these animals and organizing competitive shows in Southern California. These events include evaluations based on official standards and fun classes for pets, allowing owners to showcase their animals. The day encourages people to overcome their stigma against rats and mice, recognizing them for their charm and cleanliness.
