What's the best flea prevention for cats, and do natural collars work?

What do you think about "natural" flea collars for cats as a substitute for those made with insecticides? What cat flea collar do you recommend, if any?

Unfortunately, there is no evidence that any of these "natural" alternatives work well for fleas, and I have never seen any of my clients have much success with them. If you want to use a flea collar, I would recommend the Seresto collar - it's safe and non-toxic, and is usually quite effective for both fleas and ticks.

In short: They do not work. I suggest you do not use flea collars on your cat as there is always the danger of the cat getting hung up with the collar somewhere and getting hurt. The best would be to use a spot on for cats. There are many brands and you can search for : " Flea prevention spot ons for cats" in your browser.

The only flea collars on the market that I've found to be both safe and effective are the Seresto collars. The other flea collars at best don't work, or at worst, can cause some pretty toxic reactions. With any of the collars, it's always best to wash your hands well if you touch them. The safety margin for these collars is pretty variable depending on active ingredients and carrier mechanism in the collar. Other good flea treatment/prevention options for cats include topical medications, such as Advantage (available over the counter), or Bravecto or Revolution (prescription-based from your veterinarian).

My dog has fleas. What's the best treatment? Are flea collars safe?

The only flea collar that appears to work well is the Seresto collar. And even then, I can have a slower rate of kill for the fleas. The top products on the market our oral products such as some Perica and next guard. For most pets, these are good options that I recommend to call your veterinarian first and doublecheck. Also, you will need to treat all the pets in the household for six months to make sure you get through the entire fleet lifecycle. Best of luck.

Do vets recommend flea collars for dogs? Are they truly effective?

I think that certain flea collars can provide good protection against fleas and ticks for the right dog in the right area. Seresto is the product that I most often recommend. The collar has to stay on all the time, and bathing or swimming can alter the effectiveness of the collar, so if Mia is frequently in water or you don't want her to wear a collar all the time it might not be a good choice. Preventic is another collar, but there is concern for toxicity if the collar is ingested and there may be some concern if there are children or pets in the house that will be chronically exposed. I have also seen over the counter collars that have essential oils or pyrethrins as the active ingredient - in my opinion these don't work well. Your best bet is to ask your vet which collar they think would work best in your area.

Are flea collars safe for my 13-year-old cat? What are better options?

In my opinion flea collars are not a good idea any more (except the seresto collar) as they usually contain carbamates which are liver toxic. It would be better to use a spot on, for example. Here are some products: Spot-ons and/or chews Advantage, Advantix Advantage Multi (Advocate in the UK) Frontline (ticks as well) Bravecto spot on (ticks as well) - for cats, in tablet form for dogs Simparica, Nexgard Revolution (stronghold in the UK) Tablets: comfortis (will only kill fleas once) Collar: Seresto (ticks as well)

My dog has fleas. Are flea collars effective, or are oral meds better?

The Seresto flea/tick collar is the only one on the market that is safe and effective - the others, including Adams, are often dangerously toxic for the dog and not effective at all for fleas in my experience. Advantix is definitely a better choice than PetArmor, but the most effective option available for fleas and ticks currently would be an oral medication like Nexgard or Bravecto. I would recommend getting a prescription from your veterinarian for one of these medications, if possible - this will eliminate the need for any topical medication or flea collars, and will also work much better.

My cat has fleas, Seresto collar stopped. What's the best treatment?

Fleas can be frustrating to treat. I know that many people have a lot of success with Seresto collars, but I have not. In order to treat Bandit’s fleas, I recommend using a good quality topical product, such as Advantage (use monthly) or Bravecto (prescription based and used every 3 months). Flea shampoos are rarely effective and can cause irritation to the skin, so I tend to steer clear of them. Be sure to vacuum daily, dispose of the vacuum bag frequently, and wash Bandit’s bedding in hot water. Continue to apply flea medication regularly in order to disrupt the fleas’ life cycle to prevent a recurrence. I hope this helps and that all goes well for Bandit!

Best cat flea collar for itchy skin? Or other vet-approved solutions?

the only flea collar worth anything is Seresto. It is labeled for 8 months of prevention, but I would expect around 6 months. They have Bravecto now that is a topical and it will last for 3 months now. If those do not help you may want to look into a hypoallergenic diet also

My cat's flea medicine isn't working. Should I use a flea collar?

I'm sorry to hear you've had trouble finding an effective flea med! Most over-the-counter options are not very effective in my experience, including Advantage - although it's probably the best of the currently available OTC options! Flea collars do not work well, and can often be toxic to cats. Instead, I would recommend getting a prescription flea medication like Revolution or Bravecto from your veterinarian. This will be safe for your kitty, and much more effective. If it's been at least 1-2 weeks since you applied the Advantage, it should be safe to go ahead and use a new medication from your vet.
