Other possible causes of twitching in CKD cats include:
Affected animals may scratch, bite, lick, and chew excessively at itchy and inflamed areas. Red, oozing lesions called hot spots may develop in areas where the scratching is most intense — typically on the rump, tail, and hind legs. Affected usually exhibit thinning of the hair along the tail base in a classic, “Christmas tree” pattern. Affected cats will often remove large areas of hair and develop tiny scabs (called miliary dermatitis) that can cover most of their bodies, but affects their necks and rumps preferentially.
Most owners will first notice frequent and severe itching and scratching, hair loss, and scabs on their cat's skin. Many times the hind end is affected more than the front of the body or the head, however, cats that are suffering from an allergy to fleas can have lesions anywhere on the body. Moreover, fleas or flea dirt may or may not be readily visible.
Cats that itch often scratch excessively, chew at the area, paw at the face or show other signs of trying to relive the irritation. Itching may be the result of many problems, including allergies, infections or parasites. If your cat's itching is severe, it is advisable to contact your veterinarian for treatment. For minor itching, however, there are treatments you can try at home.Some cats do not take kindly to bathing or water of any kind. However, some cats simply love it, and if the itching is bad enough, you may be willing to try anything. Prepare a cool (not cold) bath of water and colloidal oatmeeal such as Aveeno. Allow your cat to soak (you may have to hang on to it to make sure it stays in) for about 10 minutes to relieve itchy skin.Siouxsie: Fleas are nasty little things, Cassie, and a lot of cats have reactions like your kitty is going through. I’m getting itchy just thinking about it! *grumble*Omega-3 fatty acids help relieve symptoms of itching in cats by improving skin and its ability to block out allergens. Your veterinarian can recommend a good omega-3 supplement for your cat to take. Administer the supplement regularly for best results.Your cat may be allergic to dust or dust mites. Cover your furniture and your cat's bed with plastic to eliminate dust mites and dust, wash bedding in hot water, and keep the cat away from rooms with carpet or that have been recently vacuumed. If your cat is allergic to mold, keep it indoors, out of basements and away from houseplants. Feline pollen allergies require keeping your cat indoors, at least during high pollen seasons. These steps help prevent allergic itching in your cat.In spite of common belief, a normal cat experiences only minor skin irritation in response to fleabites. Even in the presence of dozens of fleas, there will typically be very little itching. On the other hand, a cat with flea allergies has a severe reaction to even a single fleabite. This occurs because the cat develops an allergic response to proteins or antigens that are present in the flea's saliva. 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. Cats with flea allergy dermatitis (FAD) do not have to be infested with fleas; a single flea is enough to cause a problem!
