my friends cat

Question
my friends cat was fine last night at 9:00 p.m.  About 1:00 a.m. she started throwing up alot.  Her last vomit was blood.  She had labored breathing.  At 7:00 a.m., she breathed 2 short breaths and died.  Why?

Answer
Kelly,

Please give your friend my condolences!!!!!!

Remember, I am not a veterinarian! Hoe old was the cat? Was the cat spayed? If you really want to find out, you can have the cat necropsied, but my best guess as a lay person would be a heart problem.

Sad regards... Norm.
