Owen Tucker –
My cat has been flea-free since using this product. It’s easy to apply and stays effective even after she swims. No more flea bites or scratching. Works well in our rainy climate.
Oliver Buckland –
The product works quickly—no fleas within 12 hours. I noticed fewer flea eggs in the house. It’s a bit messy to apply, but the coverage is good after a few days of use.
Jasmine Mackay –
After switching from a previous brand, I’ve seen a significant reduction in fleas. The water resistance is a big plus since our cat loves to play in the rain.
Gavin Gray –
It works, but I had to reapply after a bath. The initial effectiveness was strong, but I think it might need more frequent use in high-flea areas.
