Why are my cat's flea drops not working? How to eliminate fleas?
SIGNS OF TOXICITY All flea control products are potentially toxic or may produce unexpected side effects. Toxicity may result from accidental overdose or unexpected sensitivity. Known side effects, although rare, are vomiting, diarrhea, drooling, sluggishness, weakness, or abnormal behavior. If you suspect that your animal is reacting adversely to a flea control product, stop using the product and consult your veterinarian immediately. If the reaction occurs immediately after application, the product should be rinsed off thoroughly and the animal brought to the veterinarian for evaluation. Adverse reactions may occur from minutes to days following application. Insecticides can be toxic to people; all products should be handled carefully, avoiding direct contact as much as possible. Keep all products out of the reach of children. Cats are particularly sensitive to many pesticides. ONLY USE PRODUCTS LABELED TO BE SAFELY USED ON CATS. If you have any questions about a product’s safety, please consult your veterinarian. FLEA CONTROL IN YOUR ENVIRONMENT Immature life stages of the flea accumulate in the environment when animals with fleas serve to disperse flea eggs into the environment where they then hatch into juvenile life stages. House and yard treatments need to be concentrated on "source points", which are areas where your pets spend most of their time. This typically would include the bedding and resting areas, the feeding location, etc. You can lessen the flea burden in your home by thorough vacuuming of all source points followed by disposal of the vacuum bag and by washing all animal bedding weekly in hot water and drying at high heat for twenty minutes. Steam cleaning of rugs and carpeting +/- upholstery is also helpful. In the yard, focus on areas where your pet(s) or other animals spend most of their time. Typically, fleas survive and reproduce in shaded, moist areas with plant or organic debris (under decks, bushes, storage sheds, etc). Fleas do not survive or reproduce well in sunny, open areas of lawn or patio. Elimination of yard debris will be helpful in reducing flea numbers. You may choose to utilize a professional exterminator service for the treatment of fleas in your home and garden. REALISTIC EXPECTATIONS It is important to realize that the various anti-flea medications do not eliminate the immature forms of fleas in the environment. Thus, for the first month or so you may continue to see fleas on your pet as the juvenile forms mature and search for a new host. This does not mean that the fleas have built up resistance to the medication – in reality, flea resistance to these products is quite rare. The most common reasons for failure to control a flea problem are: 1. Frequent washing of a pet treated with a spot-on product (this includes swimming in pools, lakes or the ocean). 2. Inconsistency in the application of the product. 3. Failure to treat all pets. 4. Wildlife reservoirs of fleas (feral cats, raccoons, opossums, coyotes, etc.). Thus areas below outside decks, old sheds, etc. should be barricaded or locked to discourage such ‘visitors’.

What to do when your cat has fleas: litter box, Capstar, bathing?
1. You don't need to do anything about the litter box 2. You can give them a Capstar and then the next day you can apply a topical flea medication like Advantage II. 3. You need to treat all animals in the house with a flea medication 4. You need to treat the house. I recommend Knockout Spray ES (see below) 5. You do not need to bathe the cats. It is actually better if you don't. 6. If you have a yard, I would treat the yard with Advantage Yard Spray (see below) 7. Monitor the cats for tapeworms. Cats get tapeworms by ingesting infected fleas. It may be a few weeks before you see them, if you are going to see them.

Need flea treatment for multiple cats? What's best to buy online?
If it is available, my best topical flea treatment for cats is Cheristin. It is very effective and kills fleas before they bite, which is helpful for cats with flea allergies since it is the bite they react to. Comfortis is a tablet that is also very effective, but it can cause vomiting.

Thanks for using Petco Pet Education Center, formerly Petcoach! In my opinion, the best two flea and tick preventative medications are Bravecto and Frontline plus. Any of those would be good options for him. Good luck and have a good night!
