Just wanted to thank you for responding to my post so quickly - that was very kind of you. That Holisticat site is great! Would either of you recommend using formulated natural products like these (Sinu-Rite, KC-Defense, - http://www.nativeremedies.com/petalive/
or products available on sites like www.onlynaturalpet.com
) in addition to the l-lysine? Or are they simply overpriced versions of the basic holistic remedies found on Holisticat? Again, I sincerely appreciate the feedback.
