Dear Sandra,
This is a horrible tragedy. I do not know what caused the sneezing in the first place but Persians and other cats with the Bracycephalic (pushed in) faces have shorter nasal passages and more problems with obstructed airways than other breeds.
Your cat should NOT have received distemper or any other vaccine while she had any upper respiratory issues. If she had Distemper (which I am sure she did not) the innoculation would have done nothing to decrease the severity of the disaese anyway. Therefore the innoculation was pointless.She most likely had a seizure, stroke, heart attack when you were no at home or a blood clot and one of those caused her death.
I am so very sincerely sorry for your loss. My heart goes out to you. If you have any more questions please do not hesitate to ask. I will be more than happy to help in any way possible.
very, very sincerely,
Terri
