The video shows a close-up of a group of rats inside a cage. The rats are mostly white with some black ones. They are moving around and interacting with each other. The cage is made of metal bars and has a purple base. The rats have small, round eyes and long tails. Some of them are climbing on top of each other, while others are scurrying around the cage. The lighting in the video is dim, and the focus is not very clear.
