Mavrick is so cute! Newborn kittens can be very fragile, and unfortunately sometimes some of them don't make it. The best advice I can give you is keep her warm and fed. and weigh her daily to make sure she is gaining weight. It's safe to use Frontline Spray on her to kill the fleas, so I would use that instead of bathing her every day. Be sure to disinfect the environment from the fleas, as they can be a continuing source of fleas. Wash her 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. Just keep her out of any room you use a flea spray on until it's dried completely. If there are any health problems or concerns with her, be sure to take her into a vet immediately. Best of luck, I hope this helps!

My kitten seems to be very small/underweight for her age. I believe it could have something to do with her being separated from him mother too early, but I’m not sure. I cannot figure out how old she is. Today, she started meowing and howling when I
Poor Leela. Try Frontline Spray. It's safe to use on kittens as young as two days of age. You will also have to disinfect the environment, as fleas live there, not on the kitten, and if you don't disinfect that, it will be a continuing source of fleas. Wash her 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. I'd also have her checked out by a vet today since it seems like she is in pain. Best of luck.

I've just bought 2 10 weeks old kittens and they are full of fleas what is the safest way to remove them.
There are some topical flea products, such as Frontline Plus, that are safe for kittens under 12 weeks. Give the kittens a bath using warm water and a mild flea shampoo safe for kittens. Keep them warm during and after the bath until they are fully dry! Buy a flea comb if you don't have one and comb the kitten every day or more often if you can and as needed. Kill any live fleas you find in a cup of rubbing alcohol or a little bit of the flea shampoo. Vacuum, vacuum, vacuum and throw out the bag or empty the vacuum immediately. Wash all washable blankets, sheets, sofa covers, rugs, cat beds, etc. In hot water and detergent. Apply FrontlinePlus for cats on the kitten by parting the hair on the back of the head until you can see skin and squeezing the contents of one tube onto that one spot. This is safe for kittens 8 weeks and older. For younger kittens, just bathe them with a mild flea shampoo.

I detected some fleas on my newborn kittens. I've being told that I can't use Advantage on the mother. Can I use the powder created for preventing fleas on the kittens? (Pictures below). Is it true the best way to prevent newborn kitten from fleas i
Frontline spray is safe to use on kittens from two days of age. If the kittens are that age, you can safely use it on them. It can also safely be used on Baby. You will also have to disinfect the environment, as fleas live in the home and not on the animal. 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. If you do use a spray like Indorex, do not allow Baby and her kittens in that area until the spray is completely dry. I hope this helps.

I have a kitten who is 5 weeks old and she has fleas! I gave her a bath and removed some fleas but I wasn't able to get them all. What do you suggest I do?
Since your kitten is still too young for flea meds, you can try to give her a bath using some Dawn dish soap to kill any fleas on her body. You can then use a flea or fine toothed comb to remove the dead fleas from her after her bath. Keeping her environment clean by washing bedding, vacuuming baseboards, etc can also help remove fleas and eggs from the environment to help prevent reinfection. Once she is old enough, switching to a topical preventive flea medication can help.

I have one week old kittens that were born outside when I was gone for a few days. They are eating and drink well and are very plum little ones but they have fleas what can I do to help them
You can spray their nest with Frontline Spray for cats as well as the kittens and their mother. The easiest way to do this to the kittens is by wearing rubber gloves and putting the spray on the gloves and then rubbing it onto the kittens. This should work.

How would you treat a 4 week kitten with flea anemia and severe flea infestation?
I would recommend a Dawn dish soap bath with warm water and make sure you dry Sally well. I would look for a product called Frontline Spray, which should be labeled for young cats. Once she is 6-8 weeks, talk to a vet in your area about topical products, like Revolution or Frontline Gold. I also recommend treating the house for fleas with a carpet spray. Remember to throw out the vacuum bag and treat the other pets in the house for fleas. Make sure Sally is eating a quality diet with the proper vitamins and minerals the help the anemia. If the anemia is severe, she may require a blood transfusion. Kisses to Sally!

Newborn cats in the house have fleas..I did not come across mother and dad cats..what can i do?
You can wash them in warm water and a very small amount of liquid dish soap. Use a fine toothed comb to remove dead or dying fleas. Dry the kittens thoroughly to prevent chill. Do not use any flea medications unless the label states it ​is safe for use in kittens. If the mother is around, you can use Frontline or​ Frontline Spray on her. This will not harm the kittens.

I have 3 kittens that are 5weeks old they don't have very many fleas but I don't want it to become an infestion so what can I use on them and the mother she doesn't have a real bad either they just have a few
Great question! You can use Frontline Spray on the kittens. It's safe to use on kittens from two days of age. On Beauty, you can use Revolution or Advantage. Those are spot on treatments that have been tested and proven to be safe on nursing mothers. 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. I hope this helps!

I just got a kitten yesterday. We found out yesterday that she has fleas all over her. I tried to wash her with Dawn dish detergent and got a flea comb but that didn't help at all. I don't want her to get sick. What can I do?
I would wash her again in dawn as This should kill some of the fleas. You cannot our topical flea product on her until she is at least 8 weeks old usually but this varies depending on the product you choose. If she is over 2 pounds your vet may be able to provide you will a cap star pill which will kill all the fleas on her for a 24 hour period. I would make sure she is eating and drink and playing normally. I would also take her to your vet next week to make sure she doesn’t look anemic and to see if they have anything else you can use on her. I hope this helps!
