Help Aria save Rocky - surgery needed

Rocky is my senior cat of eleven years. On 14 December we rushed to Leeds Animal Hospital with a ruptured cruciate ligament. The vet recommends an operation to remove the blockage, and the estimate came to $1,150. They have stabilized Rocky, but the treatment can't wait beyond February. Rocky is more than a pet - Rocky is a retired therapy animal who has comforted dozens of patients. I have already put $175 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 Leeds Animal Hospital's charity fund for other animals. Where the $1,150 goes: • Medication and follow-up visits: $320 • Diagnostics (X-ray, bloodwork): $250 • Hospitalization (4 nights): $580 Thanks for being kind about this. - Aria
