The most effectiveÂ way to get rid of fleas on kittens is to purchase a formula specifically designed to eliminate adult fleas from cats under four months old, while at the same time preventing newÂ eggs from developing. Consulting a vet is useful, for expert and directly relevantÂ advice.
Product descriptions should always be carefully examined to make sure that they are safe to use on kittens and not just on older cats.
It is never a good idea to use a product designed for getting rid of fleas on dogs, since these can be deadly for cats. Permethrin insecticides in particular, which are common in products intended for use on dogs, are especially dangerous to cats. While products will typically make it clear whether they can be used on cats (and kittens more specifically), it is best to read the label carefully prior to use.
In addition to getting rid of fleas on the kitten, the house should be thoroughly cleaned, perhaps in addition to using an anti-flea powder or spray. Carpets, furniture, the kitten's bedding and usual haunts will all need to be vacuumed well, after which the vacuum bag should be immediately disposed of. If there are any other animals in the house, these will also need to be treated for fleas.
As a general rule, pets' bedding should be washed every week.
