As a pet owner, it is your responsibility to make sure your pet is safe and free from fleas. To help you do that, we recommend the Johnsons 4Fleas Tablet Cat 3 Tablets. These tablets are specifically formulated for cats and kittens over four weeks of age and weighing between 1 to 11kg. What's great about these tablets is that they start killing fleas in just 15 minutes after your pet consumes them. In the first 6 hours, their effectiveness is between 95% and 100%, and complete efficiency is achieved within 24 hours. The main ingredient in these tablets is 11.4mg of Nitenpyram. It is important to administer flea treatment to your pet as soon as possible, as fleas can spread to your home and cause problems for your family. Administration is easy - mix it with your pet's favourite snack or treat, or give it directly. This pack contains three tablets, but no more than one should be given to your pet in a day. The tablets are also safe to use with other flea & worm treatments, and can be safely used on pregnant or lactating cats, as well as those who are breeding. With the Johnsons 4Fleas Tablet Cat 3 Tablets, you can easily protect your cat from fleas.
