I bought some corned beef and gave a small amount to my 19 year old cat. He bolted it down and since then has been acting sick - sitting hunched up and with neck extended. This morning I saw bright red watery vomit on the kitchen floor. I wanted to know if this was a coincidence or might be due to his eating deli meat. BTW - the vet said he was beginning to show signs of kidney failure on his last visit.
