Una MacDonald –
My cat, who weighs over 10 lbs, has not had a flea problem since using this product. It’s easy to apply and stays effective for 30 days. Even after baths, the protection remains. No strong smell, which is a plus for sensitive cats.
Zoe McDonald –
I’ve tried several flea treatments before, but this one works consistently. The cat doesn’t seem to react to it, and I haven’t seen any fleas in over two months. The application is simple and the product lasts through the month.
Nicola Bower –
Great product for large cats. Works well even after bathing. I’ve used it for three months now and haven’t seen any fleas or lice. The waterproof feature is helpful during outdoor activities.
