White worms in cats: long flat or small in feces, what to do and how to treat

Science has proven that 30 different types of helminths can parasitize a cat’s body. Some individuals spend their entire lives inside the animal, while others are forced to leave the body to complete their development process. Usually, with a small number of parasites, the pet does not experience discomfort; problems appear when they migrate or actively reproduce. Let's find out what white worms can be found in a cat's feces and how to properly carry out deworming.

What types of white worms are there in cats?

In general, this appearance is characteristic of two main types of parasitic worms:

Ascaris (i.e. “harmful” nematodes).
Flatworms (cestodes, which include all kinds of tapeworms and tapeworms).

Of course, experienced breeders know about the existence of parasitic flukes (they are also liver flukes), but the problem is that it is impossible to see them in a sick animal. To do this, it is necessary to open his liver. True, there are cases when opisthorchis or fascioli (young and simply small individuals), having “rolled” down the bile ducts, end up in the feces.

But even in this case, it is problematic to see them, and you cannot call them “white” (the body of such worms has a dark color). Thus, only two types of helminths should be considered.

White long worms: parasitic nematodes and their characteristics

In most cases of helminths appearing in animal feces, we are talking about parasitic species of nematodes. Perhaps they are the most typical and widespread white long worms.

In cats, two types are most often found:

Toxocara cati.
Toxacaris leonine.

The disease caused by them is called toxocariasis. In kittens, a similar disease is called toxoascariasis. Despite the huge diversity of species, all roundworms are similar in the characteristics of their life cycle, nutrition, and other features of their life.

Routes of infection

We should start by describing the routes of infection. Veterinarians believe that nematodes are characterized by four (!) methods of infection:

Standard, nutritional. In this case, the pet “catches” worms by eating food contaminated with parasite eggs, or by drinking equally contaminated water. In addition, this also includes cases of infection when eating intermediate hosts, which can be small mouse-like rodents, birds or even insects. It is not at all necessary that eggs or larvae of parasitic worms are present in their body: all this can be on their skin, paws, etc. It is for this reason that cats that at least periodically walk outside are many times more likely to get sick. However, parasite eggs can just as easily be brought by their owners on street shoes.

Infection... through the skin. In some species of round parasitic worms, the larvae initially lead an “honest” lifestyle, living in the upper layers of the soil. And when a cat walks on the ground, its delicate paw pads, whose skin is so thin, are in a very vulnerable state. The larvae gnaw through the skin, and then get to the nearest vessel, through which they enter the general bloodstream of the animal.

Infection through mother's milk.

Intrauterine infection. A variant characteristic specifically of parasitic nematodes (although in the case of some cestodes it also occurs). With a high intensity of invasion, the larvae can easily overcome the placental barrier, penetrating directly into the body of unborn kittens.

And it's very bad. The problem is that the invading larvae carry a lot of pathogenic microflora, and they also have problems with selectivity of penetration. It is unknown where exactly the little parasite will gnaw its way through, and it is also unknown what complications the kitten will experience as a result.

There is a possibility that as a result of such infection, the animal will subsequently develop many congenital pathologies. In addition, in such cases, the probability of death of the entire offspring increases sharply, which is always fraught with severe gynecological pathologies in the mother. Thus, a cat may well remain infertile as a result of “ordinary” helminthic infestations.

Life cycle of roundworm

Parasitic roundworms are interesting creatures. Their development cycle has long been of particular interest to researchers.

There are certain nuances, but in most species it proceeds as follows:

First, the eggs or larvae of the worm enter the animal’s body. In the latter case, as a rule, infection occurs with the direct participation of an intermediate host, in whose body the young parasites mature to a certain stage of development.

In the lumen of the gastrointestinal tract, digestive enzymes act on the shell of the egg or capsule in which the larva “hides”, after which the parasite comes out.

Although this seems illogical, the larva does not remain in the digestive tract, but immediately gnaws through the intestinal walls, heading towards the nearest blood vessels. Having broken through the wall of the latter, the parasite enters the general bloodstream.

Using the bloodstream as if it were a road, the larva travels to the lungs. And this is where the problems begin. Firstly, the parasite on its body and inside it carries a huge amount of pathogenic and conditionally pathogenic microflora, which, once in the delicate lung tissue, inevitably causes the appearance of an inflammatory focus. Secondly, the larva does not have an internal “compass”, and therefore it is far from certain that it will be able to get into the lungs. In particular, this is how some of the parasites are deposited in the tissues of the mammary glands. The problem is that the larva could just as easily end up in any organ, including the heart or liver.

The larva remains in the lungs for approximately two or three weeks. During this time, it eats well, using the tissue of the pulmonary alveoli to nourish it, growing to the required stages. The need for a “pulmonary vacation” is due to the fact that at first the larvae of these parasites need oxygen, which is not available in the intestines.

When the time comes, the body of the small parasite begins to secrete caustic and irritating substances. They cause the animal to develop a strong cough, due to which the larvae are coughed up along with sputum. Together with it, they are swallowed and enter the gastrointestinal tract a second time.

The parasite is not sent back to the lungs, remaining in the intestines for the rest of its life.

Symptoms of white worm infection

As in cases of other helminthiasis, infection with parasitic nematodes often occurs without the development of pronounced clinical symptoms.

But still, many pathologies are accompanied by constant signs (sometimes quite vague):

Bloating. This is especially pronounced in the case of kittens.
Exhaustion of the animal. This is true for cases of severe helminthic infestations. Animals in such situations literally have their ribs sticking out, which sharply contrasts with the bloated abdomen, which creates a deceptive impression of “fatness.”
Digestive problems are common , resulting in intermittent cases of diarrhea and severe constipation.
It is also possible to have a perversion of appetite when the animal eats inedible objects, as well as chalk, clay or lime. This is largely due to a lack of vitamins and microelements, which are actively consumed by the parasite’s body.

Deworming (sorry, about worms...)

Pregnant animals are prescribed in the last third of pregnancy, lactating animals - 2-3 weeks after birth, only those drugs that have appropriate indications in the instructions (for example, Milbemax), otherwise they can harm the health of the offspring.

It would be correct to drive away worms 10-14 days before mating. If this has not been done, kittens should be wormed no earlier than 21 days after birth.

Unfortunately, infection of kittens with worms can even occur in utero, during childbirth and breastfeeding.

If the animal has a severe helminthic infestation (the kitten was picked up on the street), parasites are visible in the feces, the animal is vomiting worms, then anti-worm medications should be given under the supervision of a doctor, since the simultaneous death of a large number of helminths can cause poisoning of the body and there will be a need for an IV.

White flatworms: parasitic cestodes

In cats, white flatworms are less common, but it does happen. Cestodes (that is, flat parasitic worms) in some respects are seriously different from their “round” colleagues, both in body structure and physiological characteristics:

The body of flatworms consists of many segments , each of which is a real container tightly packed with ripening eggs. Closer to the end of the body (and in cestodes it can reach several meters) there are segments with already matured eggs. Every day, thousands and hundreds of thousands of potential parasites are released into the external environment in the feces of a sick cat.

The worm grows from the head. Thus, if due to some unfavorable (for the worm) factors it loses its entire body, the head, if it remains intact, will quickly grow a new one. And this is a big problem in treatment. If to remove roundworms it is enough to use drugs that simply stun the worms and promote their natural removal from the body, then with cestodiasis it is necessary to use “serious”, poisonous drugs that kill the worm “outright”. True, the body of the animal itself also has a hard time.

Unlike roundworms, flatworms switched to a parasitic lifestyle a very long time ago, and therefore their body, in fact, is a combination of two systems: the reproductive (most species are bisexual) and the “digestive.” The name of the latter is in quotation marks because the body of these parasites only absorbs nutrients over the entire surface.

An unpleasant feature of cestodes is the way they are secured in the intestines. As a rule, parasites use peculiar hooks for this purpose, and in more rare cases, suction cups. The problem is that the strength of this attachment is so good that sometimes the remains of the worm are removed surgically!

Routes of infection

As for the routes of infection, in the case of cestodes there is only one – nutritional. Parasites enter the cat's body through food or water. The clinical picture with cestodiasis is approximately the same as in the case of infection with roundworms; there are no striking features.

Note that the body of parasitic worms secretes much more toxins than if compared with roundworms, and therefore with parasitic cestodias the likelihood of severe intoxication is much higher.

It leads to a severe deterioration in the condition of the skin and coat; in these situations, the exhaustion of the animal is more pronounced.

Development cycle

In cestodes it is much simpler. The larvae of these worms do not mature in the lungs. It is enough for them (in the form of an egg or in the body of an intermediate host) to enter the cat’s digestive system, after which their rapid growth begins. As a rule, about a month passes from the moment a larva enters a cat’s gastrointestinal tract until the first eggs appear in its feces, but much depends on the condition of the animal, the time of year, and other factors.

Causes of white worms in stool

First of all, these worms are parasites, tiny animals that live either inside your cat or on her body, and they can stay there because they feed on the nutrients your cat regularly consumes. Because of this, they will stay there as long as they have something to "eat", which is not good. What's worse is that the effects of these parasites on your cat can range from barely noticeable to miserable, even affecting her function, overall health and mobility.

That's why if you ever see white worms in your cat's poop, you need to take action immediately. Don't wait too long after you first see worms to do something about them; Your veterinarian should know this immediately in order to properly care for your fur baby. In addition to worms, you may also notice tiny eggs in the feces, and both are symptoms of the same thing: your cat has one of three types of worms. These three types include:

Hookworms : These are shaped like tiny hooks.
Roundworms : These are round and small in shape.
Tapeworms : They are longer than other types of worms and can be as large as a grain of rice or spaghetti noodles.

Tapeworms are the most common type of worm found in cats. However, all three types of worms can affect cats of any age and size, so it is important to constantly look for them.

Prevention of helminthiasis in cats

In general, prevention is quite simple, but it is far from a guarantee of the “purity” of the cat:

Firstly, it is necessary to monitor the quality of food given to the cat. All “natural” products should be purchased only in trusted places. Remember that the eggs of many parasites can withstand quite long heat treatment without problems. It is generally undesirable to use river fish to feed cats!

Secondly, deratization should be carried out regularly in private homes.

Thirdly, the house should be regularly wet cleaned, thoroughly washing the most remote corners. This way you will be able to get rid of fleas, which are mechanical carriers of many diseases.

Fourthly, at least once a quarter you need to take cat feces for analysis. In problem regions, preventive treatment of cats with anthelmintic drugs is recommended at the same time.

Fifthly, if the area where the breeder lives is unfavorable for some helminthiases, the animal’s street walks should be minimized. An exception can be made only for the cold season, when the risk of infection is significantly reduced.

Can a person get infected from a cat?

Of course it can, because a cat is the same carrier as people. Especially if the animal lives in the house. Children very easily pick up such parasites, after which serious health problems can arise. In order to avoid such problems, it is necessary to carry out preventive actions .

Keep the cat indoors.
Make sure other animals do not have parasites.
Adhere to hygiene rules.
Buy a good preventative.

Prevention products can be in tablets or suspensions, and they can be purchased at absolutely any pet store. It is also worth selecting the drug according to age, because the medicine that is intended for a kitten will not be suitable for an adult cat.

Are white worms dangerous for humans?

It all depends on the specific type of parasite. Thus, most cat roundworms are not dangerous to humans. A certain risk of infection exists only in the case of young children and the elderly, but even in their bodies the worms do not live for a long time; the immune system can handle them quite well. But with cestodes everything is not so simple.

The problem is that for some parasitic flatworms, humans can be not only the definitive host, but also an intermediate host, and this is very, very dangerous.

The danger lies in the larvae of parasites, which, having entered the body of the “lucky one,” are encapsulated in the muscles, climb into the internal organs, and even cases of the formation of parasitic cysts directly in the brain have been described.

Important! Alveococci and echinococci are deadly to humans!

So what should an owner do if he sees clumps of worms coming out of a cat in feces or vomit? First, you need to call your veterinarian right away. Secondly, when caring for a sick animal, you must strictly follow several simple rules:

After any contact with the cat, you must wash your hands thoroughly.

It is advisable to isolate the pet in a separate room, the floors of which should be washed daily, adding disinfectant compounds to the water.

It is strongly recommended to burn the feces of a sick animal! If this is not possible, the contents of the litter box should at least be packed in thick plastic bags. In this way, it is possible to minimize the spread of parasite eggs in the external environment.

When treating, you do not need to limit yourself to a single dose of medication. If the intensity of the infestation was strong, then after 10 days the pet’s feces are again taken for analysis. If even single eggs are detected, the anthelmintic treatment is repeated.

Ascariasis

But if a cat has white worms, this does not mean at all that we are talking about cestodes. It is quite possible that these are parasitic nematodes, that is, parasitic round worms. Let us emphasize once again that these worms are rarely found in feces. They, unlike cestodes, have a “fused” body, there is no segmentation, and therefore no segments are torn off. Secondly, they move very actively in the lumen of the small intestines, and therefore do not enter the feces. The exception is a particularly severe attack of diarrhea or the death of parasites from natural or “medicinal” causes.
