I have a cat that's on physician's formula prescription diet, dog that also has special food- yikes! But I've got 2 little ones in diapers so I'm always ISO similac q, huggies diapers and pull ups and stage 3 or above food qs. Don't do much in the way of pet snacks so I'll send you my doggie ones. Basically my ISO are kid (see above) and any produce or generally non-processed food (rice, beans, canned/fresh fruit, frz/fresh veggies, tofu). I'll let you know about IPs- please do the same. And let me know anything else from Sun that you are particularly interested in.
