Ollie's pyometra: help with the vet bill

Ollie is my rabbit of nine years. On 6 August we rushed to Dhaka Animal Hospital with pyometra. The vet recommends orthopedic surgery, and the estimate came to $300. They have stabilized Ollie, but the treatment can't wait beyond October. Ollie is more than a pet - Ollie walks my kids to the bus stop every morning. I have already put $15 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 Dhaka Animal Hospital's charity fund for other animals. Where the $300 goes: • Medication and follow-up visits: $15 • Emergency surgery: $260 • Diagnostics (X-ray, bloodwork): $25 If you're reading this, thank you.
