New Owner!

So we unexpectedly got a young rat and decided to keep it, I'd absolutely love it for recommendations on temporary cages till it gets older! And possibly a shopping list of stuff I'll need? Any information will be greatly needed! We do plan to get them a buddy or 2 when we figure out their gender! I do plan to get a way bigger cage when they get older but right now we just need a temporary one till then! Hoping to give this little buddy a good home ❤️
