Sick pet vet funds

I’m a teenage girl living in Wellington, New Zealand. My cat Charlie (7yrs old) has been at the vet clinic for four nights with his first undiagnosed infection. He is usually very chatty, talkative and cuddly but he has lost his meow and stopped eating. The bill has gone upto $1000, my family don’t have the funds to pay for it. I am the only one with no bills, therefore am working my hardest to try and raise money. I have a job, however I’m unable to get the funds quick enough since it’s so expensive. I’m hoping to gain some support and be able to save Charlie.
