I know many people will think it's not worth the risk, but pasteurization defeats the purpose and negates the benefits (enzymes and probiotics) because the pasteurization process kills the enzymes and beneficial bacteria. If you decide to use it, I would look for a source of raw goat's milk from grass fed goats rather than grain fed.
I've read testimonials from both dog and cat owners that tout the benefits for a variety of conditions: allergies, UTIs, kidney disease/stones, diarrhea, constipation, poor digestion, etc. In it's raw form it's loaded with probiotics and enzymes that help boost the immune system. I've been looking for a local source of raw goat's milk, but haven't come up with anything yet.
