Hi Chris. I am thinking to get the book you referred to in your post, K. Sheppard 'The Treatment of CATS by Homoeopathy'
Does the book have more on asthma, or is that the only exerpt? Also, I am thinking of getting Homeopathic Care for Cats and Dogs : Small Doses for Small Animals
by Donald Hamilton
or
Veterinarians Guide to Natural Remedies for Cats : Safe and Effective Alternative Treatments and Healing Techniques from the Nations Top Holistic Veterinarians
by Martin Zucker (Paperback -- February 2000)

Do you know anything about these books, or can anyone else recommend them?

Thanks again!
