Understanding how flea collars work and the effectiveness in cat useOwners of predominantly outdoor cats often choose this option, as it does not require treatment of the environment. Another advantage of flea collars is that they are less expensive than some of the other flea preventions available.
However, many flea collars can irritate the cat's neck, even causing fur loss. Furthermore, flea collars are often made without any elastic in them, making it impossible for cats to disentangle themselves if the collar becomes caught on something such as a tree branch. Cats have been known to choke to death in such situations, so it's important to make sure that any collar is one your cat can free itself of in an emergency. Some collars made especially for cats have special quick release catches and others have elastic built into the straps.
Additionally it is important to note that flea collars are often inadequate in situations where the cat is in frequent contact with flea-infested animals, or where there is a heavy flea infestation in the environment. Under such circumstances it is strongly advisable that you consider using an alternative method of prevention that will provide better all-over protection for your cat. Examples of such products include spot-on preparations such as Frontline Spot-On.
If your cat contracts a flea infestation whilst wearing a flea collar you must be sure to treat the environment as thoroughly as possible, and should remove the flea collar in favour of another method of prevention.
