Please Help Sunnie

My daughter found this mama cat outside with what looked like an abcess on her cheek. She had 6 new born babies with her. My daughter came to get me, and when we went back outside, it was clear she needed help. She allowed my daughter to pick her up and bring her inside, while I brought the babies. The shelter said mom and babies will be euthanized if its severe medical, and rescues i spoke to couldn't help. So my husband and I decided that we couldn't just let her stay in pain. So we put 2 surgeries on his credit card. We have run out of money to pay for anymore procedures. Turns our she got bit by a black widow, and will need to undergo another surgery to remove necrotic skin.
