- Put warm water in a bowl with a few drops of liquid detergent. Comb the fleas off of your kitten and place the fleas in the water. Swish the water around so the fleas drown.
- You can also dilute five parts water to one part bath oil and sponge or spray it onto the kitten’s coat. Then, use the flea comb to remove the fleas off her damp coat. Fleas will run from the driest parts of your kitten so they may swarm around her face. Grab them and drop them in a bowl of water so they drown.
- You can also place the removed fleas on a piece of double sided tape so they cannot move or escape. You can then drown them or crush them.
- If you have other cats or kittens, including the mother cat, in your home, always treat them for fleas as well. You do not want fleas from another animal to get back onto your kitten.

- Put on the gloves and hold your kitten with one hand, or have someone help you hold your kitten in place.
- Place the tweezers close to your kitten’s skin and grasp the tick’s head. Pull, rather than twist, the tick from the skin. Avoid crushing or squeezing the tick’s body, which will flood your kitten’s bloodstream with harmful bacteria.
- Drop the tick the jar of insecticide or rubbing alcohol to kill it. Always wash your hands well after you have removed all the ticks from your kitten.
- Apply antiseptic to the tick bites on your kitten to prevent infection. Your kitten may try to chew or itch the bites, so treat them daily with antiseptic so they stay clean. Check your kitten for any signs of a disease or infection and bring your kitten to your vet if she displays any symptoms of infection, such as fever, loss of appetite, lethargy, or stiff limbs.

Talk to your vet about tick prevention medications. There are several tick medications that you can apply to your kitten’s coat to remove ticks. However, these can cause health issues in kittens. Always check with your vet about tick prevention products before you use them on your kitten.
- If you have other cats or kittens, including the mother cat, in your home, always treat them for ticks as well. You do not want ticks from another animal to get back onto your kitten.

Understand the importance of removing fleas and ticks from your home. When your kitten contracts fleas or ticks, they do not just live in her fluffy coat. In fact, most of the flea and tick population live in any of the bedding, fabrics, or surfaces your kitten has come in contact with during the infestation.^{[10]

Expert Answer

There are two aspects to this question, the physical side (will it harm the kitten's health?) and the behavioral (will it stop the mother from accepting the kitten?). From both point of views, bathing a newborn kitten should be avoided, nor should it be necessary to bathe a newborn as the mother should lick and clean it.

Expert Answer

Fleas suck blood so a heavy parasite burden of fleas or lice could cause a life-threatening anemia. However, this requires a considerable number of fleas, feeding over a prolonged period of time, so the owner should have time to spot the problem and treat the kitten.

Expert Answer

Prescription flea products all come with a minimum age and weight that they can be used on; for most spot-ons, this is more than 8 weeks of age. There's no one answer to the question and it's best to check the product insert to see if it's safe at a certain age. Flea combs can be used from a young age, and treating the mother cat will also help control fleas.
