Hi! I have been told that Vaseline works as a hairball laxative. Does anyone know if this is true and is it safe for the ferrets? I know our Daisy will give lots of kisses if you happen to have a little on your lips - but I wouldn't want to try this without knowing for sure. We've been using Kittymalt up until now.
