As you can see, all of the above flea control products are safe to use for young pets, but the age that they can be used does vary. For very young puppies and kittens, Frontline Plus spray is probably the best option. Once the puppies and kittens get a bit older, your choices widen. Different products will work best in different situations. If you can see fleas on your puppy or kitten, you need to start flea treatment now. If you are unsure of which to use, contact your local veterinarian for help or leave a comment and we will try to help you out.

To a Flea Free pet!
