On the Feline-L list, they have been discussing red dye in
certain types of cat food that is causing cats to throw up. The most
common name mentioned was Chef's Blend, but others were as well. You
may want to check that out to see if red dye is put in Sophia's food.
Also, was it dry food that she threw up? Sometimes, they do eat it
too fast, and it expands too much for their stomachs, so they throw
it up. Since she went back for more food, maybe that's what happened
to her. I hope this info helps. Take care, and best wishes.
