Pumpkin vet bill help

UPDATE I just wanted to personally thank you everyone on this page it had been a hard few weeks I don't know how I am going to afford to pay any of it but we found he had eaten a 5p coin bless his heart but the bill is around nearer to £3,000 I have attached all relevant itemised bills all I can say is the vets have been amazing with him but I need to raise enough money to now pay for everything pumpkin had recorded I have tried my absolute best to scrape everything I possibly can the healing process is going well and I hope he makes a full recovery there are a few complications that can occur but we have everything crossed

Hello. Can anyone help me in the right direction. My cat pumpkin has been ill for a few weeks and I have been trying to get him into the vets but because I am on low income they won't see him until I have the money upfront. I have been saving up as much as possible but I can't get near the asking price. I did have insurance but because I had to get to the hospital because it was a emergency I spent some of the insurance money on a bus so it lapsed. He is flead and wormed regularly (stuff from the vets) he has lost so much weight that you can not feel his spine, he is now off his food and I know how dangerous that can be for cats and I don't want his organs to start shutting down, he is lethargic and sleeping all the time boy. With an emergency appointment it's like £163 for the appointment and god knows how much for the treatment and x-rays, blood tests I just know I can't afford it I've tried everything possible nothing, no family, no friends, no help no charity can help me at all what do I do. Who can I turn to. Please help me. Thank you for reading this.

I have set up a go fund me I hate asking for help but he is my baby boy
