Hello, I'm Dr. Deb and I'll do my best to help you today.No question, fleas are a great nuisance but there are quite a number of very effective products that are available these days to deal with them.I would most definitely NOT use Sargeant's or Hartz products since I've seen a large number of very bad, toxic reactions to these products.Personally, I like the topical products best but some are based on age of the kittens, so you have to be careful about which ones you use.Acceptable ones include:1. FirstShield or SimpleGuard for Cats which also includes a flea sterilizer.2. Revolution3. Advantage which also includes a flea sterilizer4. Advantage Multi (aka Advocate)5. Frontline Plus which incudes a flea sterilizerThere is also an oral treatment called Capstar which has a quick kill component and can kill fleas starting as soon as 30 minutes.You can bathe them but shampoos are washed off and have no residual effect to kill fleas.I don't believe that flea collars are very effective either.
Flea combs can help physically remove fleas but obviously you won't be able to remove all of them this way.If you have other pets (cats and dogs), they also need to be treated.Remember that if the kittens have fleas, then you may have fleas in your house so you will have to consider environmental control as well....vacuum, flea sprays or bombs or possibly an exterminator.I hope this helps.
