You’ve noticed that your cat seems more irritable lately, scratching a lot and getting new wounds. The main culprit would be fleasALSO known to be a cause for disease and skin irritation.

Not only does it affect your cat, but it would also affect your home as well. The ticks and fleas end up transferring to various places around your home, which can end up biting you. Also, since your cat sheds a lot of furs while scratching, the whole house would be filled with hair from the constant grooming your cat does as a way to get the fleas out.

While there are a LOT of tick and flea shampoos that help, you’ll need to maintain your cat’s fur at least once a week, and he might not even like the feeling!

That’s why instead of rubbing any home remedies or shampoo, you can try a tick collar, which uses the latest technology to keep the fleas AWAY from your cat’s whole body without the constant maintenance.

A flea collar uses insecticides, releasing a small amount of it into your cat’s body to kill fleas. The small amounts of it still say for your cat, though you can also choose natural flea collars that are less likely to contain toxins to irritate your cat’s skin or digestion (since he licks his fur).

What Are the Benefits of Using Flea Collars for Cats

It might seem a bit worrying because of the insecticides and ingredients found inside flea collars. But it has a lot of benefits you’ll still be able to wrap, such as:

Repel and Kill

Besides protecting your pet’s skin, a flea collar can also kill existing flea and ticks that remain on your cat’s fur no matter how many times you’ve washed! It PREVENTS bite marks from ticks, which can save your furry feline from suffering any form of skin condition or illness.

Easy to Use

As compared to using the usual shampoo and conditioner, or whipping up some home remedies to soothe your cat’s skin and get rid of the fleas, using a flea collar is easier to use. All you need to do is to clasp it onto your cat and let him roam free to do whatever he likes.

Long-Lasting Protection

Many flea collars can last for ALMOST a year, which saves you a lot of time and money from using various cat products. Plus, many of these collars offer waterproof or odorless features to prevent it from damage.

The flea collars are also soft for your cat, allowing him to wear it without feeling any discomfort.

How to Purchase the Best Flea Collars for Cats

Now that you know what flea collars can do, the next question is: How will you tell which one is the best to invest in? Here are some tips and factors to consider when choosing the best flea collars for cats:

1. Size

Make sure that you pick a flea collar with the appropriate size according to your cat. You can choose a smaller collar size for your kitten, or a bigger one for the adult cat.

2. Type

There are different types of flea collars to choose from according to its ingredients:

  • Insecticidal – This flea collar contains pesticides that can kill ALL forms of fleas and ticks.
  • Biological – This is a more natural flea collar with essential oils and herbs. It’s environmental-friendly and safer for pets and owners.
  • Ultrasonic – This uses ultrasound waves that make parasites anxious, making them leave the area near the collar. They are quite expensive and will need to be relaxed now and then.

3. Reputation and Customer Reviews

Make sure to choose the reputable and trusted brands such as Bayer. Also, read up on legitimate reviews (like this one!), so you know what to exact when investing in the flea collar.
