Maintaining a Flea Free Household (Infographics)

Why do my cats need flea and tick prevention?

Flea season usually begins in spring and lasts through the summer into early fall (However in many regions is last all year long). Fleas and ticks are little pests that suck on the body of the host they have latched on to. The infestation of fleas is not only irksome on the body but it is very hazardous as well to the health of the pet and pet owner. Flea protection, therefore, has been made necessary by all veterinarians.

Ticks and fleas are leeches and they can spread serious ailments through their saliva when they bite. When one latches on, it spits out a local anesthetic so the victim doesn’t feel it. Then it sucks the host’s blood.

Ticks have eight legs and initially start off head-of-a-pin small. With the more blood they suck, they grow large in size. It would be easier to locate them on a cat with light brown or white fur. In order to do that, comb the hair of your pet and clean the brush on a white paper towel and then press the dirt between two paper towels if any dark brown or black creatures with red lining can be seen on it, unfortunately, your pet has been affected.

Other methods of detecting flea can include noticing your cat’s behavior; if it constantly scratches itself; look for these pests in its fur by the above-mentioned method. Excessive and constant licking at the haircoat is another sign of potential fleas, especially in cats. Many cats will even groom the fleas out of the hair coat before you get a chance to see the evidence.

Flea control is important because flea infestations can lead to a variety of illnesses. Heavy flea infestations can lead to flea-bite anemia.  Fleas can also irritate the skin and cause flea-bite dermatitis. Some companion animals are allergic to flea bites and can develop flea allergy dermatitis.

Fleas can also transmit a variety of diseases including Rickettsia this, R. Felis, Bartonella Henselae, and Yersinia pestis (bubonic plague). Fleas can also act as intermediate hosts for tapeworms. Fleas that live on your pet can also infest opossums and raccoons, which can be important sources.

Once they emerge, an adult flea may live on a host up to 120 days. Fleas rarely jump from host to host. During peak flea season, the life cycle is about 3 weeks of flea infestation hot spots outdoors. These fleas are also harmful to the members of the house; especially children as animal-friendly children tend to interact a lot with their pets.

Cat fleas can carry the double pore dog tapeworm. This tapeworm is normally a parasite of dogs and cats, but it can infect children who ingest a cat flea that contains an immature stage of the tapeworm.

The immature stage of the tapeworm emerges from the ingested flea and begins to develop in the intestine of the child. This tapeworm does not cause obvious symptoms and is not a cause of serious disease, but you should consult with a physician if an infection is suspected.

The most obvious sign of infection in a child is the appearance of a stage of the tapeworm, known as a “proglottid,” in a child’s bowel movement. A proglottid is whitish, about the size and shape of pumpkin seed, and capable of undulating movements.

Where do fleas hide in Cats?

Fleas can hide in any place in your house which may be at your blind spot and fuzzy places such as the carpet, bedding, and couches and also is the gaps between your furniture. Fleas are in the environment as well such as in plants, flowers, and tall grass. Fleas love warm, dark, damp conditions which are why they may even be on your clothes or your laundry.

The spaces between your tiles at home provide fleas a suitable to hide and breed in. if they are left untreated for some time then they breed in the spaces they hide.

Other than the environment, the fleas obviously hide on the bodies of the pets. The armpits and groin are two areas that are warm and protected; favored spots for fleas to the hideout. The head and neck are also common flea hiding spots.

Check your cat’s ears carefully for signs of scratching, redness, blood, or dirt. These can all be signs of fleas. The skin on the belly, groin, or base of the tail may appear red and bumpy, especially if your cat is doing a lot of scratching. Excess scratching also leads to hair loss in certain regions which is why bald spots can be a sign of flea infestation.

Fleas can be found in almost every region where the weather is warm and humid in general which is why it is important to regularly clean all your clothes, furniture, yards, plants, and pets.

What Attracts Fleas in Cats?

Now there is obviously something that attracts fleas which is why they become such a menace to us but the question is what is it that attracts them?

The answer is that fleas are attracted to heat and light; they require a certain temperature and availability of light to be active and breed. In wintertime around fleas usually lie dormant so an outside infestation has fewer chances but if the fleas are in the house or already on the pet for quite some time, then they stay active as they get enough warmth and light in the place.

Fleas prefer warmer climates to cooler ones. They are most comfortable in temperatures about 65 degrees and will seek warmth in your pet’s fur, nestling close to the skin. However, this still does not mean that you can slack off on your flea protection plan.

Adult fleas are attracted to sources of light. When placed in a dark area, 93% of the fleas will move to a lighted area within 40 minutes. In natural settings, newly emerged adults will climb on top of objects within the larval habitat. They then orient themselves towards a lighted area as they wait for a host. Fleas are able to sense wavelengths between 300 and 600 nanometers (nm). They’re most attracted to wavelengths between 500 and 530 nm, which is a green-yellow colored light. Green-yellow light attracts over twice as many fleas as a standard light.

Cat Fleas Symptoms and Treatment

Fleas on cats symptoms

If your cat is constantly scratching, and biting itself most likely that it has fleas. Of course, sometimes when it has fleas it doesn’t scratch intensively. One more symptom of the existence of the fleas is a hair loss.
Also if you examine your cat carefully you will see small black grains on the animal’s body. These black grains are the blood not digested by fleas.

If you found fleas on your cat, the treatment should be immediate. To exterminate the fleas on the cat is rather easy, but, nevertheless, remember, that they are very hardy. Therefore except treatment of the cat, it is necessary to disinfect the entire house. Especially those places where the cat stays more often.

Also when using it for the first time it is better to take a smaller dose for not to cause any allergic reaction to the cat.

Besides, it is important to remember that it is not allowed to mix different means together, even if they are absolutely safe separately.

Flea & tick shampoos are rather effective and simple in use. But when using shampoo it is necessary to watch that the soapy water and foam didn’t get to the eyes, nose, ears, and a mouth of the animal. When using the shampoo sometimes it is necessary to repeat the processing of an animal in ten-twelve days.

It is also possible to use various powders and anti-fleas aerosols, but they need to be rubbed carefully in the skin and fur of a cat. If you chose an emulsion, powder, or aerosols, watch that the cat lest it should lick its fur. After all, the ingress of such preparation in a stomach can cause poisoning of the cat.

As a prevention measure against the appearance of fleas, it is possible to use bitter wormwood. This is the safest flea treatment for cats, though it doesn’t kill the fleas only frightens off them. You should crush and rub in the cat’s fur the dry wormwood leaves, and then properly to comb out your pet. You can also put cotton bags with dried wormwood in those places where the cat prefers to sleep.

And remember, if while using any natural flea treatment for cats, you noticed an allergic reaction of the cat (reddening, more intensive itching, hurried to breathe, etc.), address for the help to the veterinarian immediately.
