The collar is also adjustable to fit cats and kittens over 10 weeks old, ensuring it can be used as your kitten grows.

While the collar is water-resistant, it may not be entirely waterproof, meaning it should be removed for baths and swimming to maintain effectiveness.

Lastly, while the collar is designed to fit comfortably, it's essential to frequently check and adjust the fit, especially for growing kittens, to ensure it remains secure yet comfortable.

Featuring an adjustable breakaway safety snap, the collar helps prevent accidents if it gets caught on something.

Lightweight and easy to put on, this collar provides a hassle-free solution for flea and tick control.
