Can I use sulfur powder to cure an upper respiratory problem in a cat?

Not unless a vet tells you that you can.

It's not an upper respiratory "problem" it's an upper respiratory INFECTION which can become pneumonia and can kill a cat. If the eyes and/or nose begin running, the infection has advanced and antibiotics are necessary.
