Should I get 2 rats or 1?

Hey there, I'm considering getting a pet rat, but I'm torn between the idea of having just one or two. Could you help me weigh the pros and cons of each option? I'm curious about the social dynamics, the amount of attention and care required, and any potential challenges I might face with either choice. Ultimately, I want to make the best decision for my future pet's happiness and wellbeing. What do you think?
