Hi all! I just want to mention Nutrimalt, another cat laxative I have not seen mentioned. It is just a cheaper version of Petromalt (same ingredients) and it is in my local grocery stores, so I assume it might be in yours too. Charlotte and Kitka get about 1/2 inch twice a week to prevent any blockage/hairballs, and I tend to give it extremely freely if either of them have an other than normal poops. They LOVE it.
