Financial help in the UK

Can anyone recommend where I can get help with vet care in the UK? I have tried PDSA but I don’t live in their catchment area.

One of my kittens has had diarrhoea for a while and the vets want a fecal test done soon which will costs £280. I am currently already paying £100 a month for my other kitten who has FIP and being treated. I can’t claim on insurance as she had it before she was insured. I receive Universal Credit and housing help.

I want to help my kitten but cannot afford it this month, can anyone recommend where I can get some help??

Thank you
