Is My Cat Flea-Infected?

The most important source of cat fleas is newly emerged adult fleas from flea pupae in your house or yard.

Homes with carpets and central heating provide ideal conditions for the year-round development of fleas. The highest numbers of flea eggs, larvae, and pupae will be found in areas of the house where pets spend the most time, such as their beds and furniture. Even though fleas may be in your house, you probably will not see them.

The eggs are tiny white specks the size of dust particles, while the larvae, which are somewhat larger, with dark heads and lighter bodies, migrate deep down in carpets, furniture, or cracks in floors away from the light.

How To Find The Best Flea Treatment For Cats

Your cat’s lifestyle and parasite risk factors will determine the best flea treatment.

You should always look for cat flea treatments that are both effective and safe. And since not every cat flea treatment on the market will meet those requirements, you need to know what to look for.

According to Dr. Jennifer Coates (a Pet News Daily veterinarian advisor), cats with fleas need to be treated using a flea treatment product that contains active ingredients. These active ingredients kill fleas, sterilize eggs, and stop immature fleas maturing into adult adults.

Examples of some active ingredients that you’ll find in a quality cat flea product include spinosad, lotilaner and imidacloprid.

You should also make sure you’re buying the correct product for your cat’s life stage and weight. Also, the product must be labeled specifically for cats. Just like using the wrong shampoo, giving a flea treatment intended for dogs to a cat can be deadly.

Also, make sure that the Food and Drug Administration approves your cat’s flea treatments as animal drugs. This will help you weed out any questionable cat flea treatments.

How Can I Treat My Home Environment?

A number of different products are available which will kill the adult and larval stages of fleas and stop the flea life cycle, such as:

  • Adulticide sprays to be used in the home
  • Sprays that contain insect growth regulators (IGR) are suitable for indoor use
  • Professional pest control firms apply insecticides

Sprays for use in the house should be used in places where the flea eggs, larvae, and pupae are likely to be. The best way to treat your entire house is to first focus on hot spots, which are the cat’s preferred napping areas, such as carpets, soft furniture and beds. Once they hatch from the egg, flea larvae move away from the light and burrow deep into carpets and into other nooks and crannies where they are difficult to reach. To spray under beds, cushions and furniture, be sure to remove them. Baseboards, cracks in floorboards or between floors seams are other places where larvae may be found.

Flea eggs and pupae are extremely tough and resistant to the effects of insecticides. To remove these, as well as remove dead fleas, your pet’s bedding should be washed in hot water or replaced.

Regular and thorough vacuuming of your carpets, floors, and soft furnishings can remove a large number of flea eggs, larvae, and pupae. To prevent larvae and eggs from growing inside your vacuum cleaner, you will have to dispose of the bag. Vacuuming prior to the application of a spray to the house is recommended because the vibrations will encourage newly developed fleas to emerge from pupae, which will then be killed by the insecticide.

How to Get Rid of an Infestation

Flea infestations can be fatal to your cat and other pets in the house. Your home will need treatment, as this can prove to be the hardest part.

Flea eggs can hide in the carpets, furniture, and all over the house. When the adult fleas are killed off, their eggs are still able to hatch, and the issue begins all over again. You need to eliminate the entire lifecycle of this parasite for successful elimination and a flea-free home.

It can take up to 3 months to fully rid a home of an infestation and in some cases, you may have to bring in a professional to take care of the job. More than one treatment of the home may be necessary.

Talk to your vet to learn more about the procedure and make sure your pet is covered.

What’S The Best Flea Treatment For Kittens

The insecticides in many chemical flea treatments are especially sensitive to small kittens (especially those less than 12 weeks old).

You don’t have to treat your kitten with an insecticide or spot-on medication. Instead, simply bathe and combing them.

Here’s a video showing you how to bathe your kitten with fleas:

This video shows what happens if you don’t make a protective soap necklace while bathing your flea-riddled kitten.

If your kitten is old enough to use an insecticide treatment, it’s best to opt for an oral medication, as they’re usually safer than topicals. Sentry Fibroguard can be approved for kittens under 4 weeks old, as long as they are over 2 pounds.

Are Flea Treatments Toxic To Cats Or Humans?

All chemical flea treatment are toxic in some way – poisons that have been formulated to kill. These treatments can only be fatal to the insects, but if used correctly they won’t cause harm to your cat.

Unfortunately, this isn’t always the case. Disturbingly, flea treatments have been connected to toxicity in cats thousands of times over the years. While flea products remain on the market, some pose a danger to cats as well as humans.

And even if you choose an insecticide with a great reputation, it’s hard to predict whether or not your cat will have a bad reaction to any given insecticide.

Which is the best over-the-counter flea medication for cats?

Prescription flea treatment can also be effective, but they are safe and secure as over-the-counter remedies. Sometimes, these treatments contain previously patented active ingredients associated with prescription medications. When the patent expires on an active ingredient used in a prescription product, manufacturers of generic products may scramble to sell low-cost generic alternatives to the prescription treatment.

OTC medicines are not always considered safe. Just as it’s important when choosing a prescription product, research and careful analysis are key to choosing the right OTC medication.

The best flea treatment for cats, which is usually safer than using topical treatment, is the oral one. However, it’s not as effective for long-term management.

How Parasite Prevention is Important for Indoor Cats

Our indoor feline companions are not to be forgotten. Although many may live in high-rise apartments, and it may seem that they are much less likely to come into contact with fleas or other parasites, you’d be surprised! Indoor plants can attract all kinds of bugs (including fleas), or if you have a dog, then you 100% have a flea magnet in your home.

However, just by you’re going outside into the world, this is enough for you to bring back 1 flea (and that’s ALL that it takes!) You can host a flea party on your NYC 6-floor walk-up. It’s also a good reason to give flea prevention to your indoor cat.

Simply put, preventing fleas and other parasites is far better than trying to eliminate them once they’ve made their way onto your cat and into your life.
