Both Shelly and Tigger have the runs sense friday (ew) both of them have it off and on for awhile, it goes away for a few weeks then on again for a day or 2 then its gone again for a few more weeks.

Ive taken in fecal samples before Shelly had Geardia (sp?) when we first got her almost a year ago and Tigger had a very mild case of worms but both girls where treated.

So my question is, is there any I should ask the vet?Are there things I should look out for?
