What is Skin Rash?
The skin is the body’s first line of defense against the hazards of the outside world. When a potential invader comes in contact with the skin, such as a bacteria or fungus, the immune system fights back, sending specialized cells to the point of impact. However, when the body reacts to a substance, the body has an inflammatory response which can potential lead to an allergic reaction. Skin rash in cats is a highly pruritic condition that commonly affects the underbelly, feet, nose, ears and mouth of a cat. The underlying cause of skin rash in cats can be caused by a variety of factors, making the inciting cause difficult to pinpoint.
Skin rash in cats is an overreaction of the immune system to an otherwise harmless substance. Skin rash in cats, also known as feline contact dermatitis, is caused by direct or indirect contact with an irritant, or allergenic substance.

Symptoms of Skin Rash in Cats
Skin rash in cats will cause a notable reddening of the skin. The area affected will be irritated, pruritic (itchy), and inflamed. Common areas affected by skin rash include the cat’s anus, abdomen, toes, ears, and chin, as there is not much fur to protect the skin from the irritating substance. Additional symptoms linked to skin rash in cats includes: 
  • Papules 
  • Blisters
  • Vesicles
  • Thickening of the skin
  • Dandruff
  • Scratching
  • Biting of the skin
  • Greasy fur
  • Secondary bacterial infections
Causes of Skin Rash in Cats
Skin rash in cats is a result of a feline coming into direct or indirect contact with a substance. The immune system mistakenly takes one of these harmless substances as an intruder and releases a chemical response to the skin, resulting in an allergic reaction. Skin rash in cats can be caused by either an irritant or allergenic substance. 
Irritant Skin Rash Causes
  • Chemicals
  • Solvents
  • Topical medications
  • Detergents
  • Soaps
  • Perfumes
  • Plastic
  • Fibers 
Allergenic Skin Rash Causes 
  • Insect bites
  • Parasites (especially fleas)
  • Foods
  • Mites
  • Fleas
  • Medications
  • Plants
  • Bacterial or fungal infection 
Diagnosis of Skin Rash in Cats
Diagnosis of a skin rash in cats will require a review of the cat’s medical history, plus a great deal of communication between the pet owner and the veterinarian. Pet owners will be required to tell the veterinarian when the symptoms were first noted, where the cat spends most of her time, and what the pet owner suspects could be the cause of the skin rash. Any new additions to the home such as furniture, deodorizers, or carpeting should be noted as textile materials could be the root of the problem. Changes the pet owner has made to the cat’s food, medications, preventative flea/tick treatments, and even a new collar or food dish should be taken into consideration. 
Tests can include skin combings for fleas or flea dirt, skin scrapes for mites and cultures.
In order to make an accurate diagnosis, the veterinarian may choose to perform a patch test. A patch test is a simple test in which the veterinarian will take a sample of the suspected irritant and tape it directly on the cat’s skin. The substance will remain on the cat’s skin for a duration of time, then removed for assessment. If a rash appears underneath the taped substance, the skin rash substance has been pinpointed. If the tape test proves ineffective, the veterinarian may ask the client to remove the feline from the suspected irritant. He/she may also ask the owner to monitor the cat’s daily activities and daily diet to see if they can detect any possible causes at home. 
If the underlying cause of the skin rash remains undetected, the veterinarian may move on to perform an allergy test on the cat’s blood serum or perform a skin biopsy. 
Treatment of Skin Rash in Cats
Once the underlying cause of the skin rash has been pinpointed, the feline will need to be removed from that substance immediately. The doctor may bathe the feline with specialty shampoo to remove the particles of the substance from the skin and apply a topical corticosteroid to the cleansed skin to relieve symptoms. The best treatment option for skin rash in cats is to remove the irritating substance from the feline’s environment, but if the substance cannot be removed, therapeutic treatment will likely be prescribed.

Recovery of Skin Rash in Cats
The prognosis for a cat with skin rash varies from feline to feline. Some felines’ immune response balances out over time and the substance no longer causes the feline to develop contact dermatitis. However, other cats simply have an over-responsive immune system and pet owners may find more than one substance causes their pet’s skin to break out in a rash. The best way cat owners can keep their cat’s skin rash under control is by following the management and preventative program established by their veterinarian.

Without examining Chunky it is difficult to say specifically the cause of this rash, there are many different causes for skin problems in cats which may include infections, parasites, autoimmune diseases, allergies, chemical irritation among many other conditions. If this has been going on for this amount of time you should visit your Veterinarian for an examination, skin scrape (if necessary) and culture tests to determine a cause.

The signs that you describe can be caused by a number of things, including bacteria, fungus, or parasites. Keeping her free of fleas and giving the lime sulphur bath as directed should help her problem, and if they do not, a recheck with your veterinarian would be a good idea, as I cannot see Kunju.

There are many different causes for rashes in cats which may include parasites, infections (ringworm, bacterial etc…), chemical irritation, allergies, autoimmune disease among other causes; without examining Tess I cannot say what the specific cause is however I would recommend that you bathe her with a mild shampoo and ensure that she is treated with a topical spot on medication (a good one not the cheapest in Walmart). Also think if there are any new cleaning products or detergents used in your home which Tess may have a reaction too. If there is no improvement after bathing her, you should visit your Veterinarian for an examination. Regards Dr Callum Turner DVM
