The mite responsible for scabies in cats is the Notoedres cati, and it lives, breeds and dies on its host. Scabies is contagious because mites can move from one cat to another, or to items or surfaces that come in contact with other cats, animals or humans. Grooming can also transfer mites from one area of the body to another. The following symptoms may indicate that a Notoedres mite is living on your kitty.
-
Hair Loss
-
Scabies hair loss generally begins around the ears, then spreads to the face, eyes and neck, eventually affecting the feet and lower abdomen.
Itching
-
Besides excessive scratching, check for raw skin, especially around the ears and face.
Skin Changes
-
As scabies progresses, a cat's skin becomes thickened and wrinkled.
Crusts
-
Crusts are grayish or yellow scabs. Cats commonly reopen these crusts when scratching or grooming, increasing the risk of secondary infection.
Enlarged Lymph Nodes
-
You can check lymph nodes by feeling for "bumps" beneath your cat's skin. Pairs of lymph nodes are located in the front of the neck and shoulders, armpits, back, lower abdomen and the inside of the knee (see Resources).
