We get the little trays of seeds so you can grow cat grass from PAH, since our furbabes are indoor cats, but I'm guessing that's not quite what you're meaning? Would they really eat it of it wasn't fixed in soil of some sort? We cut the remains of the cat grass from one of the grow-tubs (which we were throwing out) so they could "finish" it, but they weren't interested. They seemed to prefer it to be as "natural" as possible, but that might just be my two.
