Feed the stray cat

HELP ME.

I found this stray cat in our building. She has this wound on her tail near the anus. I have been treating her wounds for a week now however I can see no improvement. I want to take her to the vet but I have financial issues - I’m still a student and I cannot afford her medical fees.

By your help, she may have a happy life again. As of now, I can notice that she is depress and experiencing acute pain. I never saw her play or being active.

Please help me save this cat. If you have a soft spot for cats, you can donate any amount for her treatment and food.

Thank you very much
