Flea collars work by releasing a toxic gas that fleas cannot survive. This gas kills fleas anywhere on the body of an infested cat. However, the use of this type of collars is not recommended if you do not know how to apply them correctly. In some cases, the poison released by the collar can cause harm to your cat, and some collars may even cause death.
The first thing you need to do is check the fit of the collar. Make sure it fits snugly around the neck of your cat. This will prevent accidents and discomfort. Choose a collar that is wide enough to fit two fingers between the collar and the cat’s neck. Also, choose one that has an adjustable release mechanism.
Most over-the-counter flea collars contain a variety of chemicals that work by interrupting fleas’ nervous systems. In addition, they prevent the fleas from becoming a host in a cat. Some contain insect growth regulators that are less toxic and prevent larvae from developing into adult fleas. Lastly, you can opt for herbal flea collars, which contain essential oils that are not toxic for most animals.
There are numerous brands of flea collars that claim to kill fleas on cats, but the effectiveness of a particular product will vary. Some flea collars are effective for about 90 days, while others are effective for up to 8 months. However, these products do have some side effects, including scratching, redness, and possible hair loss. These side effects usually occur within the first twelve to 48 hours after the application of the collar.
