How To Administer Prosense Dewormer

Prosense Dewormer solution is easy to administer, and it does not require a vet prescription.

For the initial dosage, the manufacturer recommends administering a ½ teaspoon per 5 lbs of body weight. Therefore, if you have a large cat, let’s say 10 lbs., you can administer a full teaspoon of the liquid.

After the initial dose, you will need to re-administer the same dosage of the dewormer after 14 days. To prevent re-infestation, continue administering the dewormer to your cat after every 30 days.

The timing of dosage is important as it determines its effectiveness in eliminating roundworms.

Give your furry friend the dewormer a few minutes after taking her meal. Alternatively, you can mix the dewormer with her favorite food and ensure that she eats up her whole meal.

If you are administering the prosense dewormer to several pets, ensure that you give individual correct dosage to each one of them, either orally or through meals.
