hi clarabeth
i have a nearly 9 week old kitten and he had his first jab last week at 8 weeks. the next is due in about three weeks time. i think the cost depends on where you live but i paid �40 for the jab and he was wormed at the same time. this was his second worming, because i took him to the vets when we got him three weeks ago and the vet de-fleed him and wormed him. i think they should be wormed when they get their first jab dont know after that, i hope this information is helpful for you.
worming doesnt cost much only a couple of pounds.
good luck x
