parasittens

Parasittens are a term used in speculative biology and some works of fiction to describe a class of microscopic parasitic organisms that inhabit domestic cats, particularly kittens, and occasionally other felids. The name blends parasite with kitten. In real-world science, there is no recognized group called parasittens; the concept is fictional or hypothetical and is often employed as a storytelling device or thought experiment.

Described variants range from protozoan- or mite-like forms to small nematode- or arthropod-like beings. In many depictions, parasittens are portrayed as translucent or colorless and highly adapted to living within host tissues, including superficial layers of the skin or other эпithelial regions. Their morphology and life strategies vary across works, but they are generally imagined as small enough to evade easy detection by the unaided eye.

Life cycles in fiction commonly involve transmission through direct contact during grooming or via ectoparasites such as fleas or ticks. They may reproduce within the host, releasing offspring into the environment, which can lead to reinfection or spread to other hosts. In some stories, environmental stages or intermediate hosts are implicated, adding complexity to the ecology of the parasite.

Host effects typically include chronic itching, dermatitis, hair loss, and changes in coat quality. Some narratives also describe behavioral changes or increased docility toward humans, though such effects are highly variable and dependent on the author’s premise.

Diagnosis and treatment are portrayed differently across works. In fictional contexts, signs are often identified through clinical observation, skin sampling, or imaging, followed by antiparasitic therapies that resemble real-world agents but with fictional variations. No formal scientific recognition of parasittens exists outside speculative contexts.
