Cats get tapeworms by eating fleas so there is a good chance that all the cats are affected but it is not a given. Tapeworms are not transmitted between cats. Most often we recommend treating with the initial dose and then repeating the treatment in 3 weeks (for all the pets). If they don't have tapeworms the treatment will not be harmful. You need to good flea control for all pets in the household and treat the home/yard environments too to prevent re-infection.

Best wishes.
