Are you sure the sensitivity is to the Science Diet Hairball formulation?
From your description, the sensitivity could be the Eucanuba, largely, as
you mention that the sensitivity only seems to occur when the Eucanuba and
the Science Diet are mixed. You state that the effect doesn't occur with
the other food / brand mixes.

Hello All!

We've got two tabbies, Spirit and Angel, each is about 3 years of age.
They both eat the same food but Angel has an on-again, off-again
sensitivity to the above food. Sometimes she'll go two weeks without
vomiting, another time it's twice a day! It always comes up yellow...so
we presume it's the food.

Is there another food, with "hairball control" that we can give her that
you'd recommend? We groom her regularly; without the hairball control
she vomits hairballs. You see, she grooms her sister, as well. Spirit
grooms Angel too, but apparently is not as sensitive.

We also give them "Eucanuba Lamb and Rice" which they both love and keep
down. For weekend treat, they love the "Fancy Feast" in the tin that we
give them. Angel keeps that down as well. It's only when we mix a small
ammount of the Science Diet with the Eucanuba, that Angel gets sick. All
suggestions will be most gratefully received!

Many thanks for taking the time to respond!
