If animals could think and go to school like humans, it would be very weird. First of all, I think they would not be able to socialize. Also, they would learn different subjects. Cats might learn how to catch mice, rabbits might learn how to stay safe from predators, and mice might learn how to escape from cats. If they went to school, they could also develop personalities. A monkey could be the lazy and funny student, while an owl could be the hardworking and successful student.
If animals could be students, they could also be teachers. A crow could be a teacher because crows are very clever animals. Animals must study hard to be successful in their exams and get good grades. All of the animals would want to be first, so there would be competition among them.
If animals could go to school, it would be very different and funny. Maybe in the future, animals will be able to go to school.
