I've raised £800 to help pay for emergency vet bills for Sid who has been hit by a car

My Sid has been struck head-on in the face by a car. He has a broken jaw, a split palate and has lost a couple of teeth. He managed to find his way back home, injured and stunned last night. This cat has been through the mill in his short three years of life. He has been abandoned ( I hand reared from 4 weeks) attacked by a dog - left for dead, but revived by steroids at 7 weeks, bitten by a feral cat, poisoned, and now this.....
I have taken in rescue animals for years , and have to say I have lost a few of my own nine lives with them... tragic accidents and illnesses have taken four of my pets from me under the age of six despite months of rehabilitation in and huge bills in some cases.
Sid is a fighter, I brought him over from Lanzarote two years ago, and he's a little toughie. The bill is going to be large and I am going to struggle to pay it because of my current circumstances. If anyone can help, I would be truly grateful.
