Cats + Medical Conditions

  • Several changes occur in the aging cat; they often progress slowly, so it is essential to have your senior cat examined by a veterinarian twice yearly. This is important so that if your cat develops a disease, it can be recognized and treated as early as possible, thereby maintaining her quality of life for as long as possible.

  • Septic arthritis occurs when bacteria or another infectious agent is introduced into one or more joints, leading to painful inflammation. The signs of septic arthritis include heat, swelling, and pain in one or more joints. There is typically decreased range of motion in the affected joint(s), as well as fever, lethargy, and lack of appetite. This handout discusses causes, signs, treatment, and follow-up care.

  • Serotonin is a neurotransmitter produced by the body that regulates mood, sleep, body temperature, pain perception, blood vessel constriction, gastrointestinal function, and even blood clotting. An animal with serotonin syndrome experiences excessive effects of serotonin. This handout reviews the causes, diagnosis and treatment.

  • Solar dermatitis is a skin disease caused by exposure to the sun. It occurs mainly in cats with white or pale patches of skin that are non-pigmented areas. The most commonly affected areas in the cat are the ears, but the nose and the eyelids are sometimes involved. Your veterinarian will recommend taking a tissue biopsy from the affected area if there is any concern that the condition may be progressing to squamous cell carcinoma.

  • Spondylosis deformans is a condition that affects the vertebral bones of the spine and is characterized by the presence of bony spurs or osteophytes along the edges of the bones of the spine. Spondylosis deformans is a chronic condition that is associated with aging and most cats show no symptoms. This condition is usually diagnosed from X-rays of the spine. Treatment recommendations depend on the individual cat and whether they are showing any clinical signs, such as pain and difficulty with movement.

  • Squamous cell carcinoma (SCC) is a tumor of the cells that make up the contact or upper layer of the skin. UV light exposure has been described as a developmental factor in people and appears to be associated with its development in cats. Areas affected include the ear tips, skin, toes, or peri-ocular region. Fine needle aspiration or biopsy may be performed for diagnosis. The metastatic rate does not appear overly clear, though staging is always recommended. SCC of the toe can occur as a primary tumor or may have spread from the lung (lung-digit syndrome). Surgery is almost always recommended in any case of SCC; the role of chemotherapy is controversial. Radiation therapy has an excellent response rate in cats with the SCC affecting the nasal planum and may give long-term tumor control.

  • Strokes are rare in cats. Some causes include a blood clot such as a thrombus or embolus that lodges in a cerebral blood vessel, cerebral bleeding from trauma, or a blood clotting disorder; however, the cause is often unknown. Signs of a stroke are variable depending on the regions of the brain affected and the degree and duration of blood and oxygen deprivation. Magnetic resonance imaging is the ideal diagnostic test for diagnosing a stroke. Treatment is complex and there is no guarantee of complete success. Your veterinarian will help you assess progress and plan remedial action.

  • Struvite bladder stones are one of the most common bladder stones in cats. In some cats, struvite bladder stones form because of a urinary tract infection. Signs of bladder stones typically include frequent urination, straining to urinate, blood in the urine, and urinating outside of the litterbox. If your cat is having urinary issues, your veterinarian will first recommend a urinalysis. Blood tests, abdominal X-rays, and ultrasound may also be recommended. Medical dissolution and surgical removal are two categories of treatment. Cats who have developed struvite bladder stones are likely to experience a recurrence later in life, unless the conditions that led to the formation of stones can be corrected.

  • Stud tail, or tail gland hyperplasia, is a condition in which the oil glands near the base of the tail enlarge. This condition causes hair loss, excess accumulation of oils in the skin and on the fur, plugged hair follicles, and secondary infections. It is more prevalent in intact male cats, as these glands are under hormonal control, but any cat can be affected. Poor grooming can be the underlying issue in many cats. Other hormonal imbalances and skin disorders are less common causes. Prognosis is generally good, especially if the underlying cause can be identified and controlled.

  • Systemic hypertension describes high blood pressure throughout the entire body. Hypertension in cats is often due to an underlying disease. When there is no underlying disease. The treatment of cats with hypertension depends on the underlying cause. Your veterinarian will recommend the best treatment options for your cat based on her specific needs. Prognosis is variable depending on how well the underlying conditions are controlled.
