Help Scout get ongoing treatment for seizures and urinary problems

Scout is one years old. He started developing seizures I took him to the emergency vet 3 times. The medications were not controlling the seizures. The vet suggested he needs to go to neurology for a MRI. I took Scout 65 miles away for a MRI Scout stayed in ICU for two days the diagnosis was not for sure could be from a botfly.Scout was released on more meds the second day he came home he was not urinating so back to vet he was hospitalized for two more days and more meds. I have exhausted my savings this has cost me over 15,000 If someone could please help

seizures due to botfly when he was a kitten before I adopted him

Very special little gut was rescued on the highway and I adopted him after my old cat passed

I am out of savings and Scout will need ongoing visits and meds
