Bayer Tapeworm Dewormer at a Glance: What Is It?

The active ingredient of the Bayer dewormer is praziquantel – a chemical that is effective against one type of intestinal parasites – tapeworms. Tapeworms are long pale worms with the bodies divided into several sectors, which act as containers for their eggs. Tapeworms suck out nutrients from the food consumed by their host, making the cat suffer from malnutrition resulting in weight loss.
Praziquantel is not a poison – it doesn’t kill the worms. Instead, it acts as a paralytic – the affected tapeworms can’t move and consume nutrients. As a result, they die right inside the body; after that, they are dissolved and excreted with urine and feces.

Unboxing and Package Supply

Bayer dewormer for cats is supplied in a screw-capped jar that is placed in a cardboard pack. One pack contains three tablets and a drug package leaflet. Bayer cat dewormer instructions are also printed on the pack. The pills are hard and relatively large, so if your kitty is stubborn or she is not used to swallowing the drugs, you’d better crush it. An easy way to do so is to place a pill in a zip-lock bag and powder it by using a hammer.

Adhere to the Recommended Dosing Schedule
