How Do Cats Get Fleas?

​This is what I wondered when I first saw a flea scurry across his belly one day while he was napping in the sun.

It can be difficult to notice fleas on cats because they are so good at taking care of their personal hygiene on their own...

To check if your cat has fleas, you can wipe a white damp cloth over its fur and close to its skin to look for flea “dirt.”

Flea dirt is actually the feces of fleas, which is the digested blood they’ve eaten from your cat. If you see red-colored streaks on the white cloth after you wipe your cat’s skin, your cat has fleas. You’ll need to treat the flea problem your cat has as soon as you can.​

When a cat ingests a flea, they can get tapeworms and flea bites can cause horrible skin diseases and allergies. For small cats, anemia can develop from blood loss.

This is aside from the fact that fleas on your cat cat spread throughout your home.

That being said, let's make sure you get the right treatments for your cats to prevent any kind of flea infestations!

What are the stages of the cat flea life cycle?

Once you have determined there is a flea problem, it is important to understand the flea life cycle so that you can truly tackle the issue head on. Surprisingly, adult fleas only represent about 5% of the population of fleas. A female flea can lay up to 50 eggs per day, so you can only imagine how many eggs are laid over just a few days.

Most of the eggs fall off of your cat where he sleeps and plays in bedding and carpeting. Eggs can also hide between wooden floor crevices. There, the eggs hatch and larvae appear. The larvae then create cocoons and may not emerge from them as adults until two years later.

When you treat your cat for fleas, you need to treat your home and surroundings as well, and you’ll need to make sure you target all stages of the flea life cycle.

When treating your home for fleas from your cat, include:​

  • Bedding
  • Carpeting
  • Baseboards
  • Outside yard areas
  • Windows and curtains
  • Furniture
  • And cat trees and play areas

What flea treatment is toxic to cats?

Possible flea treatments for cats include sprays, collars, powders, topical solutions, and oral medications. Many of these same treatments are also available for dogs. It’s critical to understand that just because a certain flea treatment works on a dog, doesn’t mean it is safe for a cat. There are many formulas for dogs that are toxic for cats and can cause death. When you are selecting a flea treatment for cats, be sure the label clearly states that the product is safe for use on cats.

Some people try natural and essential oils to treat fleas on cats. This is also dangerous because even some natural plants can be harmful to your cat. Check with your veterinarian before trying any natural home remedies for cat fleas to make sure they are safe.

Some known toxic chemicals for cats are permethrin, tea tree oil, peppermint, cedar oil, and lavender. These products cause your cat’s liver and kidneys to work overtime trying to break these chemicals down. Ultimately, these ingredients can cause liver and kidney failure in your cat!

Another concern for cat flea treatment is making sure you only use the amount necessary for your cat’s weight. Always read the packaging instructions for any product you use to determine the proper and safe dosage for the size of your cat.

What is a good flea treatment for cats with sensitive skin?

For cats with sensitive skin, cat flea pills, flea collars, and natural powders may be good choices. Cat flea pills are administered orally, and the pills typically kill fleas quickly, but you have to give them to your cat on a daily basis.

Flea collars for cats might be a good option because the collar releases the active ingredients slowly, over time. These collars may be best for cats who are already familiar with wearing collars, but if they aren’t, they’ll get used to the feeling of a collar in a few weeks.

Natural cat powders may provide relief from fleas without negative skin side effects. Look for a natural powder that you can sprinkle and brush into your cat. The extra brushing may help with any skin issues by removing dead skin cells and fur.

With any flea product that needs to be applied to your cat’s skin, it is always best to do a very small spot test first. Apply a small amount to the skin and wait a few hours to see if there is any reaction. This should be done for all products, because even well-known ingredients can cause allergic reactions for some cats.

How to get rid of cat fleas in the house?

One of the best things you can do to get rid of fleas around your home is to vacuum, vacuum, vacuum! Flea eggs and flea dirt fall into your carpet and larvae feed on the flea dirt. The sooner you can vacuum everything into a bag and get rid of it, the better. When the fleas are in the pupae stage, it is a little more difficult to vacuum them because their cocoons are sticky.

Start by completely treating your cat and making sure all adult fleas have been killed. Use can use a fine-toothed flea comb to check that you’ve gotten them all. Next, you can either use a flea fogger for a large infestation, or a spray on certain areas.

When selecting which products to use, check to see if it kills adult fleas only or if it kills fleas throughout their entire life cycle.

While you are treating your home, you can also apply Diatomaceous Earth (DE) to your yard if you have an outdoor cat. It is also safe to use indoors on carpets, but you should wear a mask when you are applying it. Make sure you get food grade DE and not the type that is for your swimming pool.

Finally, be sure to wash and dry any linens, towels, mats, or curtains that can be laundered on high heat to kill remaining fleas.

The worst thing you can do with a flea issue on your cat is ignore it. Take these tips, determine your cat’s needs, and come up with a comprehensive flea control solution for your pet and your home.
