Bartholomew has sneezed and had sneezing fits since he was a kitten. The vet always said he was fine. Now he still sneezes a ton everyday at 5 years old and now its bloody everyday. Today his eye mucus just started to contain blood and I'm worried and he sneezed up thick dark grey matter, looked like chicken! The vet ran blood tests and examined him and found nothing wrong but something must be! Help!
