Thanks for the help. It’s best if the owner finds it out or I’ll hand it to someone who can care. If nothing works, I’ll get a cage and keep it. The major concern right now is that I don’t have a cage and I’ve kept her in a quite small and dense basket. Can she spend a night in it without hassle?
This is okay for tonight, only thing to be kept nearby window / natural air.
If you decided to keep it, you need to buy a partner.
Hope, she is active. Just check her activities, droppings for diarrhea and whether she eats well.
