Help Finnigan!

Finnigan is our cat who recently accidentally injured his arm. The vet explained the surgery to fix his arm is complicated and requires a vet with experience to complete. He estimated around 3,500.00-$4,000.00. The alternative is amputating his arm for around $950.00. We spent alot on the visit including x-rays and pain medications. We need to make a decision fast so he can recover and be out of pain. This situation is breaking my heart and we really don't know what to do. This has been hard to process. Anything helps. I do not expect to reach this goal but I am exhausting all other options before we have to settle on amputation. Thank you for anyone who takes the time to read this. Again anything would help. All money raised will go towards  Finnigan's procedures and recovery. He may be just a cat but we love him dearly and I would do anything to let him keep his arm. Thank you. All money goes straight to the veterinarian, their info can be provided upon request for straight transaction.
