Sick kitty

We found a kitty with an upper respiratory infection. He is about 6 months old, we picked him up after seeing him in a post on Facebook that he had trouble breathing, and took him to urgent care. They did a bunch of tests in the vet, and also gave him meds. We appreciate any help you can give to help pay the medical bill. 

Update: He's doing better, he's associated with the other cats we have at home and plays with them regularly but still has trouble breathing, even when resting. We are still taking him to vet visits and providing medicine for him.
