Frequently Asked Questions (FAQs)

1. Do flea collars really work on cats?

Flea Collars Work Well on Cats When looking for a flea product for your cat, make sure you get one designed especially for cats. Flea collars typically work best if they have an insect growth regulator (IGR) that kills the flea eggs and flea larvae. Test your collar to see how well your cat tolerates it.

2. Do flea collars kill fleas or just repel them?

Flea collars are designed to kill fleas. Some collars target only adult fleas, while others may kill some of the younger stages of fleas, too. Some collars kill and repel fleas. This distinction matters because if a flea is repelled, it can't bite and pass on diseases.

3. How long does it take for flea collars to work on cats?

How Long Do Cat's Flea Collars Take to Work? The chemicals within your cat's flea collar are typically released within 24 hours of putting it on, and It begins killing and protecting your cat from fleas at around the three-week point, but again this depends on the type of collar you have used.
