1. Seresto Flea Collar For Cats

Seresto Flea and Tick Collar for Cats, 8-month Flea and Tick Collar for Cats

The active ingredients are released slowly and over time hence the 8 month time frame for repelling and killing fleas and ticks. A tick for the convenience factor here as it is easier than having to remember to apply flea drops once a month.

It kills fleas within 24 hours after application. It may take up to 48 hours to eliminate ticks.  Any re infesting fleas are killed in approximately 2 hours and re infesting ticks within 6 hours. Okay, so you may not remember all of this but you know someone else has done the hard work for you in this product.

Our Number 1 Recommendation is…

1. Seresto Flea & Tick Collar

When buying a cat flea collar there are three things that you need to take into account 

1.Effectiveness and Safety 



The Seresto Flea Collar passes all three with flying colors and is our number one recommendation.

Some people may be hesitant about the initial cost, however remember that the cost is for 8 month of flea protection. It actually works out to be a very small amount to pay per month.

The Bayer Seresto collar is not greasy and the slow release of the active ingredients makes it hard to beat. Just put it on the cat and it begins to work. Remember to check for any skin reactions in the first few days of wearing. Also periodically check that it isn’t becoming too tight if your cat is growing.  The ingredients are released continuously over the eight month period life span of the collar.

You are getting a quality product with the safety aspect of a release mechanism that allows the cat’s own strength to widen the collar and act as a quick release if your cat become entangled.

Cat Flea Drops are an excellent alternative to a flea collar. The drops are easy to apply and last approximately one month.

The Best Flea Collar For Cats – Things To Check

Look for a collar that has a breakaway aspect or a safety catch. This is a safety feature so that if the cat becomes entangled, the collar will break away with the cat’s body weight.

 Check to see if the collar is water resistant or if the effectiveness of the collar will be lessened if the collar gets wet.

Check the length of time that the collar remains effective and record the expiry date. Those ‘use by’ dates seem to creep up and the expiry date can come and go and be forgotten. For this reason buying more than one collar at a time is an option. There is no expiration date on a Seresto collar. Once the Seresto collar is opened the life of the collar is 8 months.

Flea collars for cats and dogs have different active ingredients and a flea collar meant for a dog can make a cat very ill.

If your cat has known skin allergies be aware of any potential irritants. As a precaution, certainly check the first few days of a new collar being fitted to ensure there are no irritating factors for the cat.

Are Cat Fleas Dangerous To Humans?

Cat fleas can cause redness and itching often around the feet and ankles on humans. It is not a pretty sight and those bites are extremely itchy. The best way to avoid this is to keep the cat and house free of fleas.

Fleas are an irritant to the cat and can cause discomfort but can also be responsible for medical conditions such as flea bite anemia, tapeworms and dermatitis.  

Children can be exposed to these parasites by playing with flea infected cats. These concerns should be taken seriously.

Homemade Flea Collar

That will depend on the brand you buy and is also reflected in the cost.The best flea collars for cats may cost more to purchase initially however they are longer lasting therefore you will not need to purchase as often.
