Relax my dear, they do not harm you or your cat and neither will the car ride. I'm glad that you will be bringing her to the vet. They will give her the proper medication to take care of the worms. It starts with one pill and then it's 7 or 10 days later,(can't remember) you give the other pill and that's it.

Keep us updated and let us know what the vet has to say about your baby girl, okay.

Wishing you and your family a Merry Christmas.
