Cats can also get roundworms from roaches that are carrying roundworm eggs. Indoor cats as well as outdoor cats. I always look at my (3) cats stools when I scoop their litter boxes because we have had round worms and all 3 are indoor only cats.
Thanks OrientalSlave, I'll do just that.
I've got back in touch with the lady that I bought Sofia from and she got straight back to me, so I take back my last comment.
Thanks for the advice everyone.
