Help Mambo the cat with his medical bills, please!

Hey everyone, my 6 month old kitten Mambo is in desperate need of medical care due to some neurological/motor issues caused by an injury/illness we are still trying to diagnose. He currently has trouble walking, can no longer jump without falling, and struggles to eat or even curl up in his favorite position. This happened so suddenly and we would do anything for him of course, but simply can't afford thousands of dollars in MRIs and other procedures. We're asking and pleading that anyone reading this to open their hearts and help out if they can so we can get him back in good health and that he can live a long, happy life with us and his brother Flynn. We've already spent everything we can, and just need some support, we don't even want to consider putting him down. He's such a happy cat and brings us such joy and deserves proper care. We're taking it day by day and hoping we can work it out somehow. Thank you all in advance for any help
