Just discovered my cats have fleas. What (if any) OTC flea remedy will take care of this issue, or do I need a Pet RX?

I can give you a flea treatment program for Daisy, and you can get them from 1800 Pet Meds without a prescription. First, I would give her Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, like Advantage ll. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash her bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. Best of luck, I hope this helps!
