Help! Kitten Vomiting!

That's not quite accurate. First, tuna does not "take away their
vitamin E". Canned tuna is *deficient* in the amount of vitamin E for
cats- it doesn't "take away" vitamin E. Steatitis (yellow fat
disease) can result from long-term feeding of canned tuna to cats
instead of properly formulated cat food, and canned tuna contains
possible allergens that may trigger immune responses. Tuna is not
acceptable as a long-term or sole diet for a cat, but using canned
tuna to stimulate appetite in inappetant cats is fairly commonly
accepted if nothing else is spurring the cat to eat. It's not
something that is *recommended* for cats, but canned tuna can serve
as a catalyst.

Thanks for clarifying that; the Vit. E and tuna issue is something I'd always
heard but really didn't know the particulars.
Another consideration, and this is just anecdotal, but some brands of people
tuna are just way too salty for me. That can't be good for cats either. I
still throw a chunk or two down to the kitchen-floor sharks when I'm preparing
tuna for me though. (The vacuum-packed foil packages are my favorites now)
