Hi all, I'm considering giving my cat Tigress slippery elm bark (she's a civvie) for cystitis. I've heard that it can help soothe the pain and also maybe prevent it as it's anti-inflammatory. I wanted to know if any of you have used this for cystitis (or anything really) and what your experience was. I also heard that maybe it should only be used short term...is that true? Thanks for any help!
