Kittens are old enough to be vaccinated for the first time at 6-8 weeks of age. Flea treatment depends on the product, as certain products can only be used when the kitten reaches a specific age. I don't recommend flea collars, they generally are pretty poor products. You can use Revolution, which is a spot on flea treatment, on a kitten at least 6 weeks of age.
