How to Choose the perfect Flea Collars for Cats?

In order to choose the best cat flea collar, you have to keep some considerations in mind. Here is what you should look at to choose the best flea collar for cats.

Natural or Chemical

To begin with, cat flea collars mostly come in 2 types, first one is those with chemical ingredients and the others are with natural ingredients.

The Flea and Tick Collars for Cats with chemical ingredients are made using harmful chemicals or let’s say chemical pesticides. These pesticides contain harmful toxins that may not only harm the health of your pets but may also turn out to be a threat against your family members’ health.

However, it has been seen that some of the flea collar brands make products that are safe for both pets and humans, such as Seresto Cat Flea Collar from Bayer Animal Health. This flea collar for kitten flea treatment contains Imidacloprid and Flumethrin, which effectively kill fleas off your cat but is not as harmful as Tetrachlorvinphos and Methoprene. Therefore, although you have to take precautions while dealing with any kind of chemical, some Flea Collars may be safer compared to others.

Moving on to the natural ones, these Safe Flea Collars for Cats are made using natural substances such as essential oils. It has been seen that natural oils contain properties that repel insects such as fleas, ticks, lice, and others. Another benefit of using natural Flea Collars for Cats is that they also repel mosquitos and make your pet safer from those mosquito bites.

Another aspect of Natural vs. Chemical Flea Collars for Cats is that chemical flea collars may be a little threatful for the environment and you but they are the more effective compared to natural or organic Tick Collars. In fact, these are the most effective cat flea collars on the market but as we know, they are usually not safe for human health. On the other hand, natural flea collars for cats have a slow function. They are usually made using essential oils that are made from natural ingredients only. These flea collars are not often the most effective but surely do their work and repel the bugs.

So all in all, if you want a flea collar that is not only safe for your cat but also for your family, go for natural ones and if you want something more effective, go for the chemical ones. Understand that all these cat flea and tick collars are made with certainty not to be harmful to cats. However, there may be some exclusions, which we have already addressed in the flea collars for cats reviews.

Pet Sensitivity

You have to make sure that the pet is not sensitive to any of the ingredients used in the flea collar. Moreover, it has been seen that some cats and kittens show allergic reaction chemical pesticides used in Flea Collars. Sometimes it may show up as bruises and sometimes as rashes. Make sure to look up for ingredients used in the pet flea collar and make sure that is not anything that your cat may be sensitive to. You may consult a vet as well for further guidance. Lastly, make sure to take sensitivity into account when choosing cat flea collars that work.

Active Ingredients

First of all, flea collar effectiveness directly depends on its ingredients. The active ingredients are those that do the majority of work of repelling and killing fleas and ticks. Although these ingredients may be poisonous for insects most of them are not toxic or mildly toxic for pets and humans.

When you purchase a cat flea collar, make sure there is mention of active ingredients on the label. Commonly, these flea collar cats ingredients would be either some chemicals or essential oils. You may choose either one, both have their upsides and downsides, however, both work fine in our opinion. Nevertheless, there are a few of the chemicals that you should not have in your Flea Collar, which we have enlisted in the first point of this section.

Collar Material

Often an overlooked aspect, collar material is as important as the ingredients that are used within. Although most of these flea collars cats are made using similar kind of material, what really differentiates them is the build and how properly they fit on your cat’s body.

Some of these flea collar cats offer a snug fit, but if not have a proper finishing, can be a little harsh on the cat’s body and in a long time due to constant rubbing on your cat’s skin, may show some wounds or rashes and even loss of fur.

Effectiveness Period

While most of the Flea Collars for Cats on the market claim to give protection for about 7 to 8 months, the majority of them do not last that long. In fact, some reviewers also claim their Cat Collar to be ineffective after the first couple of months’ usage only.

Make sure to go through the reviews of the best flea collar for cats and know how long the collar is lasting for the majority of users. Keep in mind not to get deceived by the obvious fake critics though.

Effective Against

Again, this is also a considerable feature to keep in mind while investing in a Flea Collar. Most of the Flea Collars for Cats give protection against Fleas and Ticks. However, it has been seen that some of the Flea Collars for Cats do not ensure to give protection against either fleas or ticks. Make sure that the one you invest in is effective against both.

Further, some Flea Collars for Cats also happen to give protection against flea larvae, which is a common issue when dealing with fleas. If the larvae are not disposed of, the infestation may reoccur at a certain time. Some of these flea collar cats also offer protection against, flea eggs, which can also be put into consideration.

Lastly, Flea Collars for Cats with active ingredients as essential oils naturally offer protection against mosquitos. Apparently, these bloodsuckers annoy the pets as much as they do to humans.

All in all, these are the key considerations for you to make while making the purchase of best flea collar for cats as well as best tick collar for cats.
