Nero's surgery for perenial hernias, please help

Hi my name is steve , me and my wife lucy have 3 amazing cats two of which are brother and sister rescues but sadly our boy Nero is very poorly and has had to be separated from the other two cats due to sickness. He has had a horrible start to life for a1 year old pure black cat , he has had to have two major

surgeries already due to him prolapsing and then he had to have another surgery cause he got a infection and the surgery failed and he prolapsed again and it's all been all caused by a rare parasite called trichomonas, He has been fighting everyday with the parasite which has been really nasty . Sadly we are not able to claim anything back on his insurance which has been really hard for us. He sadly has given himself a perineal hernias cause of this, which he needs surgery on to be able to live a more normal life. For the.last 9 months since being with us he has been incontinent everyday and needs this final surgery to give him a better quality of life. So far we have depleted all of our savings and we have maxed out credit cards trying to save our 1 year old boy and give him the life he deserves, his surgery will make him have a more normal life and he will be able to live freely with no discomfort and he will be able to run around with our other two cats and be the happy and healthy cat we want him to be and to have a good life. Please help save our cat. If you could help spare anything we would be utterly greatful. Thank you .
