Cat Vomit is Black

I don't really know how old my cat is cause it was a stray cat and I adopted him. I'm guessing he is about 8 to 10 years old. His vomit today was a black liquid and there was no smell to it and no pieces.



Reply from Liz (Editor): I'm not a vet, so I'm not really sure what could be causing these cat problems, but I do know in humans vomit is often colored black because it's got blood in it.

I think it's old blood that causes this - so it often occurs (again in humans) following some sort of bleed into the stomach - e.g. due to an ulcer. The blood hangs round in the stomach for a while, I guess reacts with bile etc. and changes to the black color.

You can use the Ask a Vet Online service about this, they may be able to help you more, but I think if he carries on vomiting like this, you should get him to a vet as soon as you can.

Best of luck and I hope he's OK.
