I'm trying it out, but I'm not clear whether it is good for her or not. She seems to have a small widening at the end of her colon - at the very end, it can be felt from the outside, directly on her bum, and feces remain there sometimes (but sometimes not). So I'm not sure if it's better for her to have bulkier stools, so they can move easily and get out "in bulk", which did work for a while, or smaller feces, so this part doesn't get larger :/ the vet is reluctant to call his megacolon, as the widening is very small - but it can get worse, I suppose...
