Monday is National Pet Day, and that means you have an official excuse to be as excited about your pet on social media as you want and nobody can call you obnoxious. From dogs and cats to more offbeat animals like hamsters and iguanas, there are a wide variety of nonhuman companions that people in the United States and around the world call their best friends.

There are a few other days throughout the year when you can also celebrate your pet, but today is the official National Pet Day. So make sure to leave yourself some time to give your pup or kitten a little extra love today.
