hi i have 2 cats one is fourteen and her son is twelve and are perfectly fine and healthy and they have never had any worming injections or whatever it is so why should i start doing it now?

well I guess you've just been lucky most vets will advise you that if your cats are going out doors then they should be wormed.

Mine need wormed all the time in spring/summer as they catch rabbits, birds and mice and eat them. Then they come to the door looking slim with big bellies and you know they need wormed yet again. Maybe your cats just aren't very good at hunting.

We have 3 cats. None of them are wormed or vaccinated. They only get flea treatments when we see any. They are all fine. None of them hunt as they are all lazy buggers.

Mine gets dewormed regularly because my dogs consider cat poo a delicacy given the chance

this is half the point isn't it.

your cats might be lucky and and not show symptoms from the worms. though they probably do have them. the animal that catches worms from your cat may suffer horribly.

It's bird poo that's one source of worms, so if your cat regularly catches and kills birds, they need worming and those who aren't wormed are just lucky if they don't have problems further down the line. It's known for snails to get worms as a result of wondering through bird poo, their eyes glow a white / green colour and looks revolting - it was shown in a David Attenborough programme once.

Maybe with an indoor cat it's ok, but if the cat is allowed outdoors it is advisable to take them to the vet for an annual check up.
