Help Pechy Recover.

I normally don't ask for help but Pechy went missing on Saturday May 31st. He was gone for 5 days before he was found 5 miles away from home. Unfortunately while he was missing he did get attacked by a raccoon or a coyote. My baby is resilient but it has been unexpected vet bills just to get him stitches, all of the puncture wounds cleaned, antibiotics, pain meds, and then we have to go back in a week for a check up. He is not able to walk or stand on his own right now because of the pain he is in and just the exhaustion. He is a fighter and I want to make sure I am able to provide what he needs. I have had to use my emergency fund but it will be a long road to recovery for my baby so I am asking for help.
