Labyrinthitis is an inflammation of the inner ear, often associated with vestibular disease (a condition that affects the vestibular system, which is responsible for balance and coordination). Symptoms include incoordination, falling, head tilting, and nystagmus (involuntary eye movements). Common causes are infections, tumors, or idiopathic causes, and it is often diagnosed based on clinical signs rather than specific tests. Since there is no specific cure for labyrinthitis, treatment usually focuses on managing the symptoms.
Laryngitis can happen to cats, often resulting in a hoarse or lost voice. This can occur when the larynx becomes inflamed; it can be caused by various factors, including viral infections such as upper respiratory infections (cat colds), calicivirus, and rhinotracheitis. Exposure to irritants such as dust and smoke can lead to inflammation of the larynx. Physical injury to the throat or excessive vocalization can also contribute to laryngitis. Foreign bodies lodged in the throat or tumors can also cause laryngeal inflammation.
Linear granuloma is a type of skin lesion commonly seen in cats, mostly under two years of age. It is part of the eosinophilic granuloma complex, which includes various skin conditions characterized by eosinophil accumulation due to allergic reactions. Eosinophils are a type of white blood cell that play a crucial role in the immune system, particularly in fighting infections and mediating allergic reactions. These lesions typically appear as raised, linear formations, often found on the caudal (back) or medial (inner) aspects of the thighs, but they can also occur on the neck, thorax, and forearms.
Lipomas are benign fatty tumors that can develop under the skin. Generally, they are noncancerous and should not require treatment unless there is discomfort or if mobility is affected. Symptoms include visible lumps on the skin, which can be soft and movable. Diagnosis typically involves a trip to the veterinarian, and treatment options may include surgical removal if necessary.
Lung worms are small parasitic worms that primarily infect the lungs of stray, free-roaming, and outdoor cats. Aelurostrongylus abstrusus is the most common type, which can lead to respiratory issues such as bronchitis or pneumonia. Symptoms can include coughing, difficulty breathing, and lethargy. Treatment generally involves veterinarian-prescribed deworming medications. Keeping cats indoors and reducing their exposure to intermediate hosts like snails and slugs can help reduce the risk of infection.
