Well, I'm traditionally 100% against "woo" though I usually don't say anything. However my vet suggested CBD for my cat's arthritis, and a few weeks in she's acting like she's 15 again (she's 19). So, I am willing to accept that some "woo" may work, in specific circumstances. Note: CBD seems to have an anti-inflammatory effect, possibly help with pain as well. There is definitely a lot of woo out there online, and not a lot of hard research. I don't really care how it works, my cat has been downstairs more in the last 2 weeks than she has been in the last YEAR.
