Fur Mites in Cats

Fur mites (Lynx acarus radovskyi) are parasites that live on cats’ hair shafts. They mainly cause a dull, dry hair coat. Most cats with fur mites are not itchy.

Infestations are rare and tend to occur in more tropical regions, such as Hawaii and the Florida Keys. 
 

Causes of Cat Fur Mites

Cat fur mites are not highly contagious. Infection occurs by direct contact with other infected cats or via recently contaminated environments or grooming tools.

Fur mites most commonly affect a cat’s hind end. The mites and their eggs may affect your cat’s coat in these ways:

  • Salt-and-pepper appearance 

  • Dull coat

  • Dry coat

  • Gastrointestinal disturbances

  • Rectal irritation

  • Poor appetite

  • Restlessness

  • Fever

Diagnosing Fur Mites in Cats

A diagnosis of fur mites in cats is made by plucking hairs and examining them under a microscope, as the fur mites live attached to the hair shaft Your vet may collect hair samples with adhesive tape for microscopic examination. 

Treatment for Fur Mites in Cats

Most routine flea and tick medications should be effective against fur mites. All pets that have come into contact with an affected cat should be treated. Fur mites are not known to affect humans.

The environment may be treated with products approved for flea control. However, that step may not be necessary if your cat will be treated over 6-8 weeks.
