Diarrhea in a kitten after an anthelmintic: causes, treatment

Many owners of furry pets are interested in the questions: "Why does the kitten have diarrhea after anthelmintic?", "How to stop diarrhea?". Despite the fact that modern anthelmintic drugs, which are widely available in veterinary pharmacies, clinics, and pet stores, are classified as moderately dangerous medicines and, when therapeutic dosages are used, rarely cause side effects, the substances contained in anthelmintics can provoke acute intestinal upset in small kittens. Therefore, we will consider what to do if the kitten vilifies after deworming and how to help the little pet.

How kittens become infected with worms

Owners of furry purls should remember that animals are infected not only with dangerous viruses, bacteria, but also with internal endoparasites (worms).

Important! Worms parasitizing in various internal organs and tissues are dangerous to the health and life of small kittens. Severe invasion leads to blockage, rupture of the intestines, which will inevitably lead to the death of a small pet.

To avoid invasion of kittens, every three to four months, depending on the drug used, prophylactic deworming should be carried out. An effective anthelmintic, the veterinarian will tell you the dosage.

Infection with worms of kittens occurs alimentary, transplacental way (in utero). If the cat was not proglistogonen before matingNewborn kittens are born with invasive worms. Eggs, larvae of parasites can be on the hair of the mother of the cat. Fleas, lice, ticks, and other types of ectoparasites also carry them.

Helminthic infestations are diagnosed by veterinarians not only in kittens who go outside for walks, but also in pets who do not leave the house or apartment. A kitten can eat fish, meat products without heat treatment, drink some water contaminated with parasites. Eggs of endoparasites enter the house on shoes, clothing of the owners.

What is the danger of worms for kittens

Helminths disrupt metabolism, provoke acute inflammation in the digestive tract, which leads to indigestion, diarrhea, and disrupt the functioning of internal organs. Invasive babies stunted, developing from their peers, lose weight, look exhausted.

Helminths damage the integrity of the mucous membranes, cause acute inflammation in the stomach, intestines, weaken the body of small pets, which makes it vulnerable to pathogenic microorganisms. Therefore, against the background of helminthiases, secondary diseases are often diagnosed.

Worms, regardless of their habitat, absorb nutrientscoming from food, decomposing, poison the body with endotoxins. Severe helminthic invasion can cause the death of small pets due to severe intoxication, rupture of the intestinal walls, blockage of the intestinal lumen.

Signs of helminthiases in kittens

Symptoms, the intensity of the manifestation of signs of helminthic invasion in kittens depends on the degree of infection with helminths, their localization in the body, age, resistance, general condition of a small pet.

Signs of helminthiases:

  • pallor, anemia, yellowness of the mucous membranes;
  • violation of breathing, heart rhythm;
  • decreased appetite, complete rejection of food;
  • unstable stool;
  • poor coat condition;
  • itching in the anus;
  • copious discharge from the nose, eyes;
  • lethargy, decreased activity;
  • allergies, skin rashes.

Foamy diarrhea, diarrhea with blood, vomiting after eating, drowsiness, weakness, refusal of your favorite treats are obvious signs of helminthiases in animals.

As already noted, helminthic invasion is very dangerous, so if you notice one or more of the above symptoms, if the pet’s condition worsens, the kitten reacts poorly to external stimuli, becomes lethargic, inactive, consult a veterinarian regarding treatment. It is necessary to carry out therapeutic deworming as soon as possible to your beloved pet.

Why do kittens vilify after anthelmintic

Diarrhea (diarrhea) - a condition characterized by frequent bowel movements, the release of watery, paste-like feces. If the kitten begins to vilify after anthelmintic and diarrhea lasts no more than 24-38 hours, this is normal. In this case, diarrhea is a protective reaction of the body, which can be triggered by substances containing in anthelmintic.

In addition, some components of anthelmintics enhance peristalsisintestinal motility to accelerate the natural process of removing intestinal parasites from the body of animals.

If the kitten is badly vomiting, mucus, blood, foam in the feces, particles of undigested food are visible, and at the same time intestinal upset occurs in the first hours after deworming, the kitten is most likely infected with endoparasites.

It is possible that if a small pet is swallowed after taking an anthelmintic, the pet is infected with a viral-bacterial, intestinal infection. Therefore, vaccinate and anthelmintic can only be clinically healthy pets. Weakened by pathology, disease, infection, the body tolerates worse such preventive and therapeutic manipulations.

Important! If, after prophylactic, therapeutic deworming, in addition to acute diarrhea, the kitten has vomiting, nausea, itching, weakness, apathy, muscle cramps, salivation, allergic manifestations, this condition is provoked by individual intolerance of the components of the medication.

Profuse diarrhea in small kittens after anthelmintic occurs in the case of using fake medications, improperly selected drug, violation of the therapeutic dosage recommended in the annotation.

therefore before deworming, consult a veterinarian regarding the dosage and choice of medication. Be sure to carefully read the instructions. In case of exceeding the dosage in animals, side symptoms (diarrhea, vomiting, nausea, unstable stools) very often develop.

Other reasons

Often, diarrhea after anthelmintic in kittens can be caused by others reasonsthat the owner of a small pet missed or disregarded.

Diarrhea in kittens after treatment and prophylactic deworming can be caused by:

  • poisoning;
  • poor-quality feed, stale products;
  • a sharp change in regime, diet;
  • stress, severe fear;
  • viral and bacterial infections, exacerbated by the background of helminth infections; low-quality, contaminated drinking water;
  • dysbiosis;
  • congenital pathologies;
  • intestinal infections;
  • wool accumulated in the stomach.

Therefore, if a pet begins to vomit after taking anthelmintic drugs, analyze what caused diarrhea. Perhaps the upset stomach is absolutely not caused by the anthelmintic, therefore, in order to begin adequate treatment, you need to establish the exact reason intestinal upset.


If your pet has an upset stomach after medical, preventive deworming, but the pet is active and looks completely healthy, the stool should normalize within the first two days after the anthelmintic.

The same goes for the other collateral symptoms Therefore, always after taking anthelmintic drugs, any other medications, carefully monitor the behavior and condition of the little pet.

Advice! If diarrhea is accompanied by vomiting, depression, weakness, profuse salivation, allergic manifestations, a symptom uncommon for a healthy pet is noticeable, invite a veterinarian to your home or take the kitten to a veterinarian.

With an upset stomach, which is provoked by anthelmintic drugs, hold the baby for 6-12 hours a hungry diet. In this case, the kitten must have access to fresh boiled drinking water.

Important! Loperamide, Chloramphenicol, anti-emetic drugs should be given to kittens with extreme caution, after consulting with a veterinarian. Exceeding dosages will cause serious complications and consequences for the little pet.

If, after an anthelmintic race, the cause of intestinal disorder lies in viral, bacterial infections, complex therapy is prescribed, which involves taking antiviral, antibacterial, anti-inflammatory, general strengthening drugs. To normalize the intestinal flora, probiotics, prebiotics, enzyme agents will be prescribed. Treatment is carried out until the pet has fully recovered.

How to worm a kitten

In order to avoid indigestion after the treatment-and-prophylactic deworming, for the anthelmintic of a pet, use only special antihelminthics for kittens in suspensions, tablets, powder (Prazitsid, Prazitel).

It is best to use drugs of a systemic, wide spectrum, the action of which is aimed at all types of worms, since without analysis it is not always possible to visually understand what type of endoparasitis a pet is infected with. As a rule, all anthelmintics for kittens need to be given repeatedly, so carefully read the instructions for the medication.

Important! Anthelmintics can only be given to completely healthy kittens. weighing at least 500 gr. If you pick up a kitten on the street and doubt that the pet is healthy, show it to the veterinarian.
