UPDATE on his emergency visit yesterday:

He does have a UTI & is on Clavaseptin 750 mg BID. His bills were $438.09, and thanks to an anonymous Titan angel, they generously paid his bill. Unbelievably kind and heartwarming. 

Eagleson Veterinary Clinic recommended a recheck in about four weeks’ time, and if the adoption is approved, this is something the approved adoptive home can easily manage.
I was told he was a ‘star’ patient, and I would have expected nothing less!
