Help Siggy the cat with Urgent Surgery

Siggy is a stray cat who visits frequently at a support home and who is loved by all the residents. He comes and goes frequently. When he came back this past weekend, he was limping and was taken to the vet yesterday. We were told that he would need his back leg amputated as there was no way to reset his leg. Hoping to raise enough money for him to have his surgery so he can continue to bring joy to others that love him so much.
