Some vets are nice and don't charge an office fee for getting de-wormer. I can go into my vet's office any time and get most meds without even bringing the kitty in. Drontal (kills all types of worms) usually costs around $4-$6 per pill.Where were yiu able to deworm for $6? I just recently discovered my two cats have rapewirm (brought in by the new cat) and I too am strapped for cash
