Nala's a tumor on the spleen: help with the vet bill

Nala is my tabby kitten of six years. On 11 August we rushed to Seville Veterinary Centre with a tumor on the spleen. The vet recommends an operation to remove the blockage, and the estimate came to $1,500. They have stabilized Nala, but the treatment can't wait beyond September. Nala is more than a pet - Nala walks my kids to the bus stop every morning. I have already put $125 toward the bills and asked for a payment plan. Whatever I can't raise, I'll repay to anyone who needs it back. If more is raised than needed, the surplus goes to Seville Veterinary Centre's charity fund for other animals. Where the $1,500 goes: • Diagnostics (X-ray, bloodwork): $155 • Emergency surgery: $1,050 • Hospitalization (3 nights): $295 Ask me anything below before you decide. I'd rather you were sure.
