Parasites can live in or on our pets. There’s a surprisingly large number of them, and they’re potentially hazardous to the health of our furry friends and family.
But how much do you know about the different types of parasites, and the danger they present?
Inside or outside? Where to find parasites in dogs and cats
Cats’ parasites (and Dogs’ parasites too) can be split into two vast groups–internal or external. In scientific terms, that’s endoparasites and ectoparasites, respectively.
Endoparasites, which live inside the animal are usually of the wormy variety. Tapeworms, roundworms, hookworm, whipworm, and heartworm all feature.
Healthy pets with just a few worms might show no symptoms at all. But endoparasites can cause anything from an upset stomach and coarse coat to severe illness and even sudden death, as is the case for heartworm. Some very common cat endoparasites are zoonotic and can put people at risk.
Ectoparasites on parade–the usual suspects
Ticks, mites and fleas in cats are the external parasites of greatest concern. Let’s take a brief look at what they are, and the threats they pose.
Sandflies are well-distributed in southern Europe and carry a protozoan parasite responsible for causing leishmaniosis. For dogs, sandflies are a serious and life-threatening parasite that can also affect humans. Did you know that, even though sandflies are mostly found in southern Europe, they have been recently discovered in northern European countries such as Germany?
Ticks are a group of bloodsucking external parasites that includes a dozen different species. Some important ticks in Europe are the castor-bean tick, by far the most common; the meadow tick, which transmits many grave diseases; and the brown dog tick, the only tick species that can reproduce indoors. These parasites that belong to the same class as spiders are of particular concern because of the diseases that can be transmitted from their bites to both people and pets, such as Lyme Disease. They are becoming less seasonal in many parts of the world, including Europe, and may soon be an all-year-round threat. Parasite expert Christina Strube has commented:
“ONE OUT OF FIVE TICKS WE HAVE SEEN CAN BE A CARRIER OF SOME ILLNESS”
Fleas are wingless, blood-sucking little insects, with a flattened body on the sides,that can jump 160 times their body length with their powerful legs! Fleas occur across Europe with the exception of northern Scandinavia and the highest points of the Alps and the Pyrenees. They are particularly common among cats, dogs and small mammal pets, such as rabbits, but they can also be found on birds. Fleas cause itching and scratching, and they also bite people which is of particular concern as they can carry diseases that infect both people and animals, such as bartonellosis or cat-scratch fever. These parasites can be very distressing for the pet and the owner, so they can erode your relationship with your pet.
Since fleas can survive indoors, they can infest your home and be very difficult to get rid of. In fact, only adult fleas live on pets, spending 95% of their life as immature fleas, hiding and lurking in your home. To ensure your home and your family are safe, year-round flea control is required.
Mites are a diverse group of external parasites that cause mange in pets and people. Mostly, they cause skin lesions of varying degrees of seriousness. These can occur anywhere on your pet, but some types of mites attack specific areas of the body, such as the ears.
Lice come in two different types– sucking and chewing. The former are blood-suckers and infestations can potentially cause anemia. Heavy chewing louse infestations cause skin lesions. In addition, some lice can carry and transmit tapeworms.
