School is officially back in session. Students all over the country are back in the classroom, and you may notice that some of these students are a little furrier than others.

Scrolling through the magical world of TikTok we came across a ton of videos of fluffy friends on their best behavior in class.

What are some benefits of having pets in the classroom?

According to Pets in the Classroom, some of the benefits of having animals in class are that they can instill responsibility in students, bring awareness to feelings and needs of others, and can generally lessen tension in class. Plus, they're just so darn cute.

Are animals allowed in classrooms?

Schools must give authorization to allow animals on the property. Unless, it's a service animal. The Americans with Disabilities Act permits students with disabilities that use a service animal meeting the ADA definition to have the animal at school.

From paws to pencils, here are some adorable videos of the cutest classroom companions.
