My cat has round worms and they won't go away?

Question

We've been treating my cat for round worms for months but we can't get rid of them. We give him the treatment and scrub all of his things and then a week later they're back. I don't know how to get rid of them. What can I do?

Answer 1

Are you sure they are roundworms?  Are you using the right meds?  Did you get them from a vet?

If the answers to these is no- or I don't know- see your vet

Answer 2

Take the cat to the vet. Don't count on over the counter products to kill the worms and eggs.  

Answer 3

go to the vet
