My kitten has fleas. Can I use Advantage if I don't know their age?

You can put it on them, and keep each one in a separate room for the next 24 hours until it dries. Then they won’t kick it off each other. Be sure to apply the Advantage to the very back of their heads where they can’t reach it to lick off themselves.

Since it's been two weeks since you late applied the Advantage, you can try another dose of it. He can also have Capstar again. Be sure to disinfect your home, as that will be a continuing source of fleas. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. Best of luck, I hope this helps!

No, per the label instructions cats have to be at least 12 weeks of age. If you are having a flea issue I suggest you use a topical flea medication like Advantage II. This can be used on kittens 8 weeks and older. Do not use the lesser brands like Hartz or Sentry - there have been many reactions to those brands. Hope this helps.

Revolution can be used on puppies 6 weeks of age and older, and there is no minimum weight requirement. At 7 weeks old, he can use Advantage II if the puppy weighs at least 3 pounds, or K9 Advantix II if he weighs at least 4 pounds. If you prefer a flea collar, the Seresto collar can be used on puppies at least 7 weeks of age or older. After he is eight weeks old, you can use Activyl, or Frontline Plus, as well as some of the newer oral flea control medications such as NexGard and Trifexis.

Cute kitty. This is likely a flea and actually you can bathe kitty as early as 2 weeks of age, since that is when most kitties can regulate their own body temperature. Fleas are very small and move very fast. They can cause itching and also they can carry tapeworms which can come out in the stool and look like little grains of rice. And actually Pinky is old enough for topical Revolution flea prevention, which is ok to give to kitty’s who are at least 6 weeks of age. Ask your vet for a prescription, since this is not available over the counter. But you can go ahead and bathe Pinky now, just blow dry him a bit to speed up the drying process if it is cold temperature where you are. I hope this helps and best wishes with your kitty and these fleas. Take care.

Hello. Yes, this should be very safe as long as the Advantage drops are appropriate to the size & age of your kitten. Vaccinating a few days later will not cause any problems. Thanks for using Petco Pet Education Center, formerly Petcoach.

If it's been at least two weeks since you applied the Sergeant's, which it has been, it's safe to apply the Advantage now. You will also have to disinfect the environment. Wash their bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home.
