8 best bayer cat flea treatments

Bayer is a well-known company that has produced flea treatments and products for cats to help pet owners manage and prevent flea infestations. Some of the key information about Bayer cat flea treatments includes:

  1. Advantage II for Cats: Bayer's Advantage II is a popular flea treatment for cats. It is available as a topical solution that is applied directly to the skin on the back of the cat's neck. Advantage II is designed to kill fleas on contact and provide month-long protection against reinfestation. It also helps control and treat lice infestations in cats.

  2. Seresto Collar for Cats: Bayer also offers the Seresto collar for cats, which is designed to provide long-lasting protection against fleas and ticks. The collar releases active ingredients that kill fleas and ticks upon contact.Seresto collars are known for their convenience, as they offer up to 8 months of continuous protection.

  3. Other Products: In addition to Advantage II and Seresto, Bayer may offer other flea control products for cats, such as sprays or shampoos. These products are typically designed to be used in combination with other flea control measures, such as regular cleaning and vacuuming of the cat's environment.

  4. Veterinarian Guidance: It's essential to consult with a veterinarian before choosing a flea treatment for your cat, as the best product may depend on your cat's specific needs and any existing health conditions. Veterinarians can recommend the most suitable and effective flea control options.

  5. Regular Flea Prevention: Flea prevention is crucial for the health and comfort of your cat. Fleas can cause skin irritation, allergic reactions, and transmit diseases. Regularly using a reliable flea treatment can help keep your cat free from fleas and protect them from related health issues.

Please keep in mind that product availability and formulations may have changed since my last knowledge update in 2023. When considering a Bayer flea treatment or any other product for your cat, it's advisable to check the most recent information and consult with your veterinarian to ensure the safety and efficacy of the product for your specific pet.

User questions & answers

Question: Is this 6 month supply a 6 pack of tubes
Answer: Hi Doreen... Actually, I bought the 4 pack because I have four cats. I had earlier in the month bought a 4 pack someplace else, so I had two treatments for each cat. I did the treatments three weeks apart (the instructions say it is OK to do if you wait seven days). I bought the 9+ lb. package as three of the cats are well over that weight. One cat is a bit smaller and I didn't use quite all of the tube on her. None of the cats had any bad reactions, and it worked well for three of them. The other cat (partial Maine Coon) had some results, but not so good.
Question: Does this kill ticks? If not, what do people recommend for ticks
Answer: To get rid of fleas and ticks use Frontline Plus. I started to use it on mine a year ago it killed the ticks and fleas. I reapply it every other month and I haven’t seen one since.
Question: When using this medicine, do I also need to flea bomb or spray the apartment ? Or will the medicine kill all fleas in the apartment, as well
Answer: VACUUM EVERY DAY. Or at least every other day. You will NEVER get rid of all the fleas if you don't treat the environment as well as the animal(s). In addition to the Advantage II, I used Knockout spray and also shampooed my cat. She has now had two doses of the Advantage and I have been spraying and vacuuming every other day and I finally feel like I have the upper hand! Even when you think they are gone, keep treating your cat and house. All it takes is one flea to start an infestation.
Question: Why is the item called "Bayer K9 Advantix II Flea and Tick Control Treatment for Cats"? The Bayer K9 is, of course, for dogs
Answer: Please be sure to use ONLY Feline Advantage on cats and use ONLY the dog Advantage on dogs! The use of canine Advantage on cats WILL kill them giving them severe neurological damage! I wish that Advantage would make the packaging TOTALLY different for cats and dogs, it would help. Especially with people who may not see the difference at first glance. My elderly mom accidentally applied the large dog Advantage to her cat and it had to be put down. Mom has felt horrible about it. Awful experience. Also about dosing, I have a 19 year old cat and I have used feline Advantage on him every summer for about 3 months for well over 17 years. It works wonderfully for him. I have always used the large cat product but since he has lost some weight this year I called Bayer and asked if I should use a smaller dose. The person at Bayer explained that Advantage works on body AREA as well as weight. So even though my cat has lost some weight (he's 9 pounds) his body AREA is still the same (loose skin) and so I have been applying the large cat dose and it has worked well for him this summer with no ill effects. I cannot speak to the authenticity of this Amazon product as I purchase my Advantage from the local pet store.

User questions & answers

Question: Can this be used on kittens
Answer: Cheristin products do not have an expiration date on them. This is because they are controlled by the EPA, not the FDA. The EPA says that because these products are produced with 5 years of shelf life and that they are packaged in either 1 packs or 6 packs, it is reasonable to assume that they will be used within 2 years and therefore no expiration date on the packaging is required.
Question: Do I need to separate other pets
Answer: Not that I have noticed, but I have sinus issues so may not be as sensitive to smell!
Question: i couldn't find the product for kitten less than 1 pound (about 4 month). can this one work
Answer: No. Cheristin is for cats only.
Question: Does this come in 4 dose
Answer: Yes rhis one is only a single dose however you can get 6 pack doses as well usually around 70 to 80 bucks but its well worth the money.

User questions & answers

Question: Would i be able to use this on my one adult cat, shes very small and 1 year old
Answer: If you cat weighs 9lbs or just a little more (like 10-11#) it would be safe. Just be sure to accuratelyweigh her before usinging it. If she weighs more than 11 lbs then use the correct product and donate the other (for small cats) to a rescue or your local SPCA.

Answer: I use the Advantage II for cats over 9 pounds. It is easy to apply, works great, is waterproof ,and is a must have for my active Muffin. I purchase the 2 month supply. This is a great bargain for Advantage II. The kitten Advantage II May or may not be as effective for larger cats. I suggest using the recommended weight product. Hope this helps...

Answer: Imidacloprid and pyriproxyfen. I used this on my rabbits with no ill affect.

User questions & answers

Question: Does this product also kill ear mites and mosquitoes as Revolution does? Thank you
Answer: This doesn't even kill fleas.
Question: I accidentally bought the the 5-9 lb. size for my cat that weighs 13 pounds. Should I use 2 tubes instead of one
Answer: No, just use one. You may have to re-apply after 2-3 weeks but that is perfectly safe according to my vet.
Question: Expiration dates
Answer: No exp date since there is no heartworm prevention in this there is no need for an exp date and as long as you follow the recommendations for temperatures to store it in it should be good and effective indefinitely
Question: hi, is anyone that uses this actually seeing the dead fleas on their floors? like advantage 2? thanks need 2 no
Answer: Its kept my dog flea free. Best yet, she's deathly allergic to Fipronil flea meds suddenly as a senior. Advantage and this generic have produced zero side effects in her, although I was terrified to use anything after a terrible reaction to her usual flea products last summer. With a new puppy, a 1 year old, and 2 cats, skipping flea prevention wasn't an option. So far, this has been wonderful. By the way, if your pets show any signs of an immediate reaction to any flea products, immediately bathe them in blue Dawn dishwashing liquid. I'd changed vets and the new vet failed to tell me all the regular shampoos weren't helping because flea meds are oil based. Only Dawn will get it off, hopefully before it's been absorbed in the bloodstream. Dawn and 2 weeks of subQ fluids even 4 days later saved my dog's life.
