Any petrolatum (Vaseline etc.) product
can, potentially, dissolve the "fat soluble"
vitamins (A,D,K ) and keep them from
being absorbed. This is why most hairball
meds contain added vitamins and/or
fish liver oil. The notion is that they are
so loaded with these that they won't
absorb them from the food or even provide
some. Other products that work by
providing more fiber might prevent vitamin
absorption by speeding the gut contents
along before the vitamins can be absorbed.
Clinically I have not seen these as a
problem, but who knows what evil
luuuurks in the gut of cats?
