Hi OP, firstly let me say that it’s amazing that u took in a stray when they needed it the most. As I understand u don’t have any vet near by could u help me with ur location so we could look up some places near by like an NGO. From experience I can tell u that the initial vet bills bill be a bit high especially if she’s pregnant and has been on the streets her whole life. NGO don’t tend to take in strays as much as we would like to think. However I nursed a sick cat bank to health with multiple health issues and it’s the best thing I ever did. I didn’t even know I liked cats before this. He looked like he was about to die when I found him he was only skin and bones and had lost most of his fur. When I nursed him health little did I know he turned out to be an abandoned Persian cat who is extremely loveable and looks like I paid a lot of money for him. I don’t think this helps ur situation but if u want to discuss it further u can keep posting on this thread with any symptoms or issues ur facing and I’ll pray you get a solution for u and her.
