Can Dog Flea Collars be Used on Cats or Vice Versa?

Canine-feline owners, about every product, from toys to food to medication, happen to wonder whether it can be used for both of their pets.

And therefore, the internet is deluged with their naive yet some climacteric questions.

I chose two of those repeatedly asked must-have-certified-answers questions to answer:

  • Can dog flea collars be used on cats? Can I use a cat flea collar on a dog?
  • Can small dog Seresto collars be worn by cats? Can you use a Seresto cat collar on a small dog?

I’ll answer these questions from every aspect why you should not even think of using every sort of dog’s flea collar on the cat or vice versa.

So without lingering further even for a second, let’s dive into the article with a simple rule of thumb.

There is a simple rule of thumb: don’t mean something for something if it’s not meant.

Only use flea products meant for cats on a cat or vice versa.

Cases Reported

Flea products for a canine should never be used on a feline, nor should feline flea products ever be used on a canine.

This philosophy should be used for all sorts of medicine.

If you’re thinking of using a product, in this case, a flea collar, purchased for your dog on your cat, make sure it says on the label “for dogs and cats”.

If it does not, you should not risk your cat’s health.

There have been cases reported where the person switched (accidentally, unknowingly) dog and cat flea products, and the animal died from poisoning or ended up falling severally ill.

Even when using a flea or tick collar correctly on the animal it’s intended for, you should watch for signs of poisoning. We put a flea and tick collar on one of our dogs, a large healthy mixed breed, about ten years ago. After wearing the collar for just a few hours, he fell ill with poisoning symptoms and died. There was nothing we could do.

Product Composition

The chemicals for killing the fleas on the collar for the dogs are stronger than the ones on the collar for the cats, and they will make the cat sick and may even kill it.

No, don’t ever think to use it. The ingredients are used in the dog flea collar are designed especially for dogs, and it may harm if used on cats.

Skin Difference

Dogs do not have the same biology as a cat or as a human. Cats can have extreme allergic reactions. Please consult your vet if you have any questions. You should be able to find what you need at a pet store. Never assume what is okay for a dog to be okay for a cat.
