for my girls? I had given it to Walter, Thumper and Fonzi at one point when I noticed they had a problem, but I'd like to be sure with the girls.I have chewable tabs...so it's possible I have the same kind you do. I know it works, just not when to start it. My two are really active and don't seem to have any problems right now, but it would be great to give as a preventative before anything goes wrong.
