Ok well mom cat definitely has roundworms.
Making an appt today for parasite stuff as the one vet around me has a nice coupon for a free check up and will see the whole litter for 20$ + meds/tests.
On the phone the vet receptionist said they give actual meds for the worms and they have Revolution there as a preventative. On the site for the Revolution and Advantage it said it kills the roundworms.
So uhh...why two meds?
She also said they do not use revolution on cats under 8 weeks but it was fine for a nursing mother. (website said 6wks is ok)
