I've been feeding small pieces of saltine crackers to Kiki every now and then. I wipe off all the salt and I only do it occasionally. I wouldn't think it'd hurt her. I could always go out and buy crackers with no salt and such, but it's so much easier to use saltine crackers becaues we always have them in the house anyway. She loves it, but if it's not OK at all, I will most definitely stop. What do you think?
