My cat is 2 years old, male, short hair street cat and his first time to a real vet hospital and came back from the vet tonight and still has trouble breathing without oxygen he breaths too fast even relaxed, he got pneumonia from throwing up and inhaling it over the weekend what should i do to get his breathing back to normal or take him back or go to a different one because the one i went to is expensive and get a second opinion?
