Oliver needs your Help

Oliver got away from us when our house burned to the ground on Feb. 9th this year.  I have been looking ever since then and have posted in Lost and Found, PawBoost, Facebook and numerous other venues.  A sweet woman saw him along a greenway and posted to the Black Mountain Exchange where I was alerted.  I went looking for him and finally found him but he didn't look like the same cat.  He is emaciated, dehydrated, kidney levels high, mouth ulcers, respiratory infection, and eye infection.  He is at MedPet Emergency Hospital and so far we have spent $3200 in 2 days.  He will need to stay there for 5 or more days until he is able to eat on his own and his kidney levels come down.  Any little amount would be greatly appreciated and Oliver would be most grateful to know he has so many people that care about him. The rate I was given by the Hospital is going to be $850 +or- a day because of feeding tubes, IV fluids, heating blanket, urine, and blood test to monitor his kidney levels.  Thank you in advance.
