The other night, my white, indoor/outdoor cat came into my room and sat in my lap. Just before she moved, I noticed a small insect on her coat. I grabbed it and determined that it was indeed a flea. IMMEDIATELY, I gave her a bath with flea/tick shampoo and made sure to wash excessively around the area where I spotted the flea. The shampoo supposedly kills fleas on contact, and their eggs and also repels them. After her bath I put the flea drops on her and also put a brand new flea collar on her. Today, I noticed her scratching excessively around her neck and inspected her to make sure she has no remaining fleas. I didn’t see any, however I know they are quite quick. Our vet told us awhile ago to wipe a damp cloth on her coat and if it turns rust/red colored she has fleas. I did this and was unable to determine if she did or not, as she also has a tan patch (dirt) around her neck. What can I do to determine if she has fleas, and to further rid her of them, if they are on her
