Parasites

  • Mange is a parasitic skin disease caused by microscopic mites. Two different mange mites cause skin disease in dogs. Demodectic mange, sometimes just called 'demodex' or 'red mange', is the most common form of mange in dogs. Demodectic mange most often occurs when a dog has an immature immune system, allowing the number of skin mites to increase rapidly.

  • Dipping for demodectic mange may be done by the veterinary health team, or at the owner's home. These instructions will help the dog owner treat their pet for mange in their home.

  • The ear mite is a surface mite that lives on cats, dogs, rabbits, and ferrets. It is usually found in the ear canal but it can also live on the skin surface. Ear mites are a common cause of ear disease and infection. Infestations are a very common problem in puppies and kittens, although pets of any age can be affected.

  • Encephalitozoonsis is an infection that can affect the kidneys, eyes and nervous system of rabbits. It's caused by an organism called Encephalitozoon cuniculi or E. cuniculi, a small microsporidian parasite that's intracellular (it has to live within another cell).

  • Demodecosis is a parasitic skin condition, caused by demodex mites. These microscopic mites can be found on the skin of all animals, but in some cases they proliferate to excessive levels and cause clinical signs. While demodecosis is more common in dogs than cats, there are two species of demodex mites that can affect cats: Demodex cati and Demodex gatoi.

  • Feline upper respiratory infection (URI) is one term for a respiratory infection caused by one or more viral or bacterial agents. Synonyms for this condition include feline infectious respiratory disease and feline upper respiratory disease complex (URD).

  • Ferrets commonly get infestations of an ear mite called Otodectes cynotis. Many ferrets show no symptoms of infestation. Subsequent problems of the ears are rare. Ear mites are acquired from other affected animals at the breeders, in pet stores or animal shelters.

  • An allergy occurs when the cat's immune system overreacts or is hypersensitive to foreign substances called allergens. When a flea bites a cat to consume a blood meal, some of its saliva is injected into the skin. In an allergic cat, just one bite can result in intense itching that can last for days. Many flea-allergic cats chew or lick the hair off their legs. Since the flea saliva causes the reaction, the most important treatment for flea allergy is to prevent fleabites by treating the cat and environment for fleas. Corticosteroids can be used to block the allergic reaction and give immediate relief to a cat suffering from the intense itching of FAD.

  • Flea allergy dermatitis (FAD) is a leading cause of allergic reactions in dogs. It is the antigens or proteins in the flea saliva that cause an intensely itchy response to sensitive dogs. Itching and hair loss in the region from the middle of the back to the tail base and down the rear legs (the flea triangle) is often associated with FAD. Strict flea control is essential in the prevention and treatment of FAD. Occasionally corticosteroids are used to reduce the itching in patients with severe signs of FAD.

  • The most common flea found on cats and dogs is the cat flea, although any species of fleas, including fleas from rabbits, squirrels or other wildlife, can be found on cats. Even though fleas may be in your house, you probably will not see them. Fleas need to be eliminated from 1) your cat, 2) any other cats and dogs that you have, 3) your home and yard. Although most topical insecticides kill adult fleas, many have limited effectiveness because they only work for a few hours after application. Ensure that the product is labelled for use in cats, as some dog products may be poisonous to cats.
