Flea collars don’t have a complicated working. These are simple collars that contain insecticide to kill the fleas as well as ticks present on the cat. These collars work in two different ways. Some collars release a toxic gas that can kill the fleas and ticks immediately and further prevent any fleas and ticks from occurring again. Other flea collars release a substance that dissolves on the fatty layers of the skin of the cat and spreads throughout, thereby killing any ticks present.

The first way tends to be more ineffective because it usually only works for the fleas that are in close distance of the collar. This way is often used by the cheaper collars. The second way is more effective and safe to use. However, you generally need a prescription from the vet to use it.
