My Dcat has worms. She is on a four week worming/ flea spot on from the vet. She isn't due to get it again until Saturday.
In theory she should still be covered from last dose. Do I give it a whole week early? Contact the vet to see if she should be on different product or maybe dose? She was weighed at last check up. She is 12 and I don't want to take chances with her. Is a worm poo count for cats a thing?
No vet open today so just posting for advice.
