If I give my cat capstar how soon is it safe to start a longer-lasting topical flea treatment? Which topicals are safe to use - any, or just select brands?

Because cats are so sensitive to flea medications, I would wait at least two weeks before treating Missy again. You can give her Capstar now, however. It's a one time pill that starts killing fleas in 30 minutes and is safe to give now. You can give it again as needed during these two weeks :-)
