I have a few cats with sensitive tummies, and one who sometimes has really loose stools, and I've been feeding SD Sensitive Stomach now for about 1 1/2 months, and it's really helped them. At least I think it's helped them because I don't see as much barf as I used to, and the one with the realy loose stools has been having more normal ones for a while now.

Good luck to Kalypso, and hope she feels better in her tummy soon!
