I've got three cats. They all have some kind of worm infestation. Would I necessarily need to bring all three in? Our could I possibly get enough meds for all my kitties?? And does anyone know how much this will cost me?? Approx.

They told me I could bring in a stool sample and they would give me enough medicine to take care of all of my cats

I'd Highly recommend that you take all three of them in! But call them and ask how much it would be, as prices for Animal Treatment varies.

Call them

You'll have to call them, im not sure. But ive had cats and kittens infested with worms and we put a clove of garlic and a dash of tumeric in their food everyday abd it got rid of them. You can also put food grade diatomaceous earth in their food, about a table spoon.
