my cat has worms. do I have to sketch it to vet or get over the counter meds?

Definitely go to the vet

Vet

you can go to pet smart petco or pet supermarket take a pic of the worms and tell them they have over the counter worm meds for all worms or they have them that are for certain worms but don't take it to the vet a lot of wasted money when over the counter worm meds are just as good and a lot cheaper

I used to work at a vet clinic. Over the counter meds don't work for pets.

over the counter meds worked almost instantly for my cat, he had tapeworms
