Yeah, we had to give Tierce an anti-nauseant so he could keep the Atopica down. It's the castor oil, so I've been told.
We've tried everything from raw to Purina Hypoallergenic to Acana to Orijen, but it doesn't seem to make a difference. Each diet we tried out for a minimum of 4-6 weeks. Now he's on Acana, which doesn't do anything for his allergies, but he seems to do well on it otherwise.
