I recently asked my sister (who's a vet tech) this question. Zoee was eating Taz's everyday for a while, but has stopped now . And she said there is stuff you can get to sprinkle on the cats food. But I don't think it was Accent. I think it was something you had to buy at the vets or maybe a pet store. I'm glad she stopped though because I didn't want to mess with Taz's food since I just got him eating again this year.
