Cat Parasites Internal and External

Internal cat parasites

Flatworms or Taenias:  Very varied, they are common cat parasites in adult cats and can be transmitted by fleas, by the consumption of slaughterhouse waste, fish, viscera of rabbits and various rodents. Segments of worms allowing the multiplication of the tapeworm is released in the stool of the animal. When they are visible, they can denounce the presence of the worm. However, in the case of the tapeworm Echinococcus, responsible for the man’s hydatid cyst, the worm segments are not visible. In this case, regular treatment of animals is important. Roundworms are of primary importance: they are the leading cause of malnutrition, rickets and mortality amongst young people. Despite their size (up to 30 cm), usually they are noticable in the stool only after deworming.

Hookworms and whipworms:  Not visible in droppings so requires deworming protocol for a cat 15 days before mating and then 15 days before farrowing. Then, during the lactation period, at the same time as her kittens. For the stallion, before and after breeding. In kittens, from the age of one month up to 6 months, once a month then spacing every 3 months until the age of 18 months. Do not forget to deworm the mother at the same time as the kittens. For adult cats, they should be wormed every three months, especially if the cat hunts (mice, birds, …) or is fed with uncooked meat. For products to use, ask your veterinarian for advice that will tell you the best for your cat.

Fleas are responsible for skin problems as well as transmissions of internal parasites.


Ticks:  They can parasitize dogs, wild animals, occasionally cats and sometimes humans. Whatever the stage of their life (adult, larva or nymph), ticks spend only a few days on the host. They eat their meal by consuming their blood. The eggs and all the rest of the cycle are on the ground. Infestation can only occur from young fasting ticks directly from the environment to the host and not from one animal to another or to a human. Only the larvae live as parasites on animals and sometimes on humans.

Ear mites:   Also known as otacariosis, the parasitic mite, is the Otodectes cynotis. It lives and reproduces in the ear canal and feeds on cerumen, leaving a smelly brown/black deposit. The symptoms are hot ears, red, sensitive to touch and frequent scraping, and wounds from those can become infected and spread. The treatment will last several weeks to eliminate parasites from the adult phase to the egg. It is imperative to treat all animals in the house. Your veterinarian will prescribe the necessary products. It is not transmissible to humans so do not panic.

The dermatophytes:  They have very varied clinical manifestations, and are therefore difficult to diagnose, especially as there is a significant rate of healthy carriage. They are very common especially in Persian cats, as well as in guinea pigs (T. mentagrophytes in 30% of guinea pigs).
