This product is suitable for kittens and cats over 1.5 lbs and at least 8 weeks old, making it versatile for various life stages. Additionally, its waterproof formula ensures it remains effective even if your cat gets wet, which is beneficial for active or outdoor cats.

It's important to note that some cats might experience temporary skin irritation at the application site.

Advantage II Small Cat is a popular flea treatment formulated specifically for small cats weighing between 5 and 9 pounds and aged 8 weeks or older. It contains active ingredients Imidacloprid and Pyriproxyfen, which work together to kill adult fleas, larvae, and eggs by direct contact, helping to break the flea life cycle. Applied topically at the back of the cat’s neck, this method is straightforward and does not require pills or prescriptions, making it convenient for most cat owners. The treatment begins killing fleas quickly, within 12 hours, and provides protection for a full month. It is fragrance-free and becomes water-resistant after 24 hours, allowing cats to tolerate some water contact without reducing its effectiveness.

This product is designed specifically for small cats, so following the weight and age guidelines is important for safety and proper dosing. While it effectively controls fleas, it does not specifically repel ticks, which might be a consideration in tick-prone areas. Applying the treatment involves parting the cat’s fur and squeezing the entire tube onto the skin in one spot, which might be challenging if the cat is uncooperative. This makes it a reliable and vet-recommended monthly flea prevention solution for small indoor or outdoor cats.
