Just a note - I am glad you are concerned about the long term affects of Science Diet!!! Of course, the most important thing is to get your babies stabilized....Ann Martin wrote a book called Food Our Pets Die For and it discusses the pet food industry's unethical practices...Its worth a glance at the bookstore.
I also would recommend Dr. Pitcarin's book, I trust him and have used it sucessfully on many occasions.
I might consider consulting with a holistic vet, just so that you have a voice on the other end of the line to consult with...at
AHVMA - Home you can do a search to find a local holistic vet. Many will give you reduced rates for phone/ email treatment, which is often as effective as hands on treatment.
