How you can control worms

Intestinal worms in cats are very common and it is difficult to see if your cat has worms.  Worms can be picked up from many places, from hunting and eating rodents, other animals’ faeces, from grooming and ingesting fleas and also from humans entering the house, unwittingly carrying the odd flea or egg on clothing or shoes.  This wormer works by killing worms that are in your cats gut, so to prevent worm reinfection, it is recommended to worm your cat regularly for both tape and round worms every 3 months.  If your cat is a hunter, it is more at risk through eating infected rodents and you may wish to consider worming your cat more frequently as every month.

Kittens can contract worms from their mothers’ milk and require more frequent worming.  It is recommended that kittens are wormed every 2 weeks until they are 8 weeks old.  At 8 weeks they can be wormed monthly until 6 months and then this can be reduced to every 3 months.  For pregnant and nursing cats it’s recommended to worm at the end of the pregnancy and once during lactation with the kittens first worming treatment.

Controlling worms is only part of protecting your pet and your family against harmful parasites.  Provide your pet with effective flea and worm treatments regularly, to combat external parasites such as fleas and internal parasites like the roundworm Toxocara canis that can be passed to humans. Regular treatments help break the lifecycles of these parasites, helping to keep your pet and your family healthy and pest free.
