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 own body weight.

Check to see if the flea 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.
