I know when I'm feeling cold all the time then I probably need iron.
Slow-FE is time-release iron and easier on your gut, but it seems some doctors don't know about
it so don't suggest it (no Rx needed).
That's how I found my Naturopath, a homepathic vet gave my cat accupuncture and probiotics for a "hot gut" that was causing her to pull her hair out and it worked so well I asked for a referral. I know my other cat gets a little colitis once in a while, too. Go figure.
