Help Pay Party's Medical Bill

My neighbor's cat, Party, had a seizure yesterday April 17th, and today had 2 more only 3 hours apart.

All the emergency vets around us were demanding thousands upfront or were closed, and the only one we managed to get in touch with charged an absurd total of $3,684, which they had no choice but to sign up for a credit card to pay off over time. Please help me pay their cat's medical bill, they've just paid off their car and now have this bill to worry about on top of their cat's well being.
