If Blood Was Coming Out A Cat's Mouth And Died . What Would Of Been The Cause ?

That happened to my friend. I was just looking online for something now that might be able to tell what it was. Apparently her cat let out a scream, fell of the arm of the chair and started vomiting blood and frothing at the mouth. He died few minutes after. =(

I wish I could find out what it was because she saw this happen and it might give her some closure. She can't stop thinking about it.

There are a lot of possibility. Bleeding can be a sign of internal problems.Cats with chlamydia, a bacterial infection that starts in their upper respiratory tract, will often have swollen and bloody gums. Leukemia, kidney disease, and cancer can also cause the gums to bleed. So can an immune system disorder called thrombocytopenia, which damages the cell-like structures in the blood that aid in clotting.

This just happened to my cat and the cause on autopsy was heart worms.

This happen to my cat and the vet said it was probably a busted blood vein in her head. So sorry I know how it feels.
