yep,,, adding just a bit to her regular food is how most do it and then more each day... If you had her on the bland diet, and she did ok with that, I'm more apt to switch faster than suggested... that's me, but if I were 'you'I would wait for some better answers .. I did many switches when younger, and fairly fast even then... but so far, Hanks one of the rare ones with a good tummy..
