Help 2 homeless rats get basic needs

hi, a few days ago I saw 2 rats on our apartment’s yard. I tried to catch them, I also told my landlady and she managed to catch them in the end. Right now they’re with me and I have them in a temporary box with some bedding, food etc..but I don’t have the funds to take care of them. I contacted a rabbit and small rodent shelter, as well as post some posts into Facebook rodent adoption groups but I didn’t get a response. I need some funds for basic things like a cage, food and bedding. I’m gonna take care of them until I can find someone to give them too but I don’t know how long that is going to take so right now the main problem is the cage because I can’t let them free roam.
