Medical bills for Stalin

My precious Stalin had a sudden respiratory issue and needed to go to the emergency vet's office. He had to spend the night there under constant supervision and in a respirator, followed by some examinations after he stabilized. The tests didn't find anything specifically wrong with him, and he quickly recovered to his original happy state, but I am looking at quite a big bill from the vet as I didn't have him insured at the time (he is now!)

Any help in covering this vet bill is greatly appreciated. Here's a photo of the vet's bill:


Thank you!!
