Here at GJW Titmuss we offer a wide range of cat wormers at very competitive prices. Cat wormers can only be dispensed by a suitable qualified person, so when you purchase cat wormers from our site, you will need to enter your cat weight and age, so we can make sure the correct dosage is being supplied.Furthermore it is advised that an adult cat should be treated for worms 4 times per year. There may be certain instances however where more regular worming treatment is desirable.It is also good to remember that different wormers kill different types of worm. Piperazine, for example only kills roundworms and hookworms, whereas Drontal Cat wormers Plus controls all intestinal worms found in cats in the UK.
