Best Flea Collars for Cats

There is so much to love about our feline friends, but fleas are not one of them. Fleas and ticks seem to have a special liking for cats but as pet owners it is important to prevent and treat the problem before it gets out of hand. If you’re looking for an alternative to tablets or “spot on”  treatment types, flea collars may be the answer. Flea collars are an easy and low maintenance option; put it on your cat and forget about it for six to eight months. There are also chemical free or all natural choices to choose from as well.

Flea collars can be a safe and effective way to prevent your cat from getting fleas, whether he is exposed on a daily basis or only on occasion. It’s important to pick out the right flea collar for your cat so that you and your kitty will be comfortable and pest-free.

How Do Flea Collars Work?

Flea collars provide an easy way to deliver the active ingredients needed to kill and repel fleas and other parasites. Some collars offer continuous coverage over your cat’s body.

Newer technology allows collars to work by releasing a controlled amount of the active ingredients from an area of high concentration and storage (the flea collar) to low concentration (your cat’s hair and skin).  The collar slowly releases active ingredients throughout your cat’s body over time. Fleas are killed when they make contact with the active ingredients. This process continues until the collar needs to be replaced. It is important that the collar be applied and fitted according to the brands provided instructions.

    I just bought a Seresto collar for each of my cats last night. We decided against one for the youngest who manages to escape collars no matter what. She’ll stay on ointment, a generic to Advantage.
    I’ll report back!
