Internal Medicine

Chronic Kidney Disease (CKD) is very common in senior cats. CKD leads to increased thirst, urination, weight loss, and lethargy due to the gradual loss of kidney function.

Acute Kidney Injury (AKI) can result from toxins (like ingesting lilies) or infections, leading to rapid kidney damage.

An overactive thyroid gland, usually due to a benign tumor, causes symptoms like weight loss, increased appetite, hyperactivity, and sometimes vomiting and diarrhea.

Often seen in overweight or older cats, diabetes leads to high blood sugar, increased thirst, urination, and weight loss. Management usually involves insulin and diet control.

Inflammatory Bowel Disease (IBD): Chronic inflammation of the GI tract that can cause vomiting, diarrhea, and weight loss.

Pancreatitis: Inflammation of the pancreas, often linked with IBD, can lead to intermittent vomiting and lethargy.

Asthma: Common in cats, especially those with allergies. Causes coughing, wheezing, and difficulty breathing, especially during flare-ups.

Upper Respiratory Infections (URIs): Often due to viruses or bacteria, leading to sneezing, nasal discharge, and sometimes fever.

Hepatic Lipidosis (Fatty Liver Disease) can occur when a cat stops eating, often due to stress or illness, leading to fat accumulation in the liver, jaundice, and lethargy.

Cholangiohepatitis causes inflammation of the bile ducts and liver tissue, causing vomiting, jaundice, and lethargy.

Hypertrophic Cardiomyopathy (HCM) is a common heart disease in cats, especially in certain breeds, causing thickening of the heart muscle and possibly leading to heart failure or blood clots.

Hypertension (High Blood Pressure) is often secondary to kidney or thyroid disease, causing potential damage to the eyes, heart, and kidneys.

Feline Lower Urinary Tract Disease (FLUTD) is a group of conditions affecting the bladder and urethra, often causing difficulty urinating, blood in urine, and sometimes obstruction in male cats.

Urinary crystals or stones can form in the bladder, leading to discomfort, frequent urination, and, in severe cases, blockage.

Feline Leukemia Virus (FeLV) and Feline Immunodeficiency Virus (FIV) are viral infections that weaken the immune system, making cats more susceptible to infections and other diseases.

Toxoplasmosis is caused by the Toxoplasma parasite, it can cause fever, lethargy, and muscle weakness, especially in immunocompromised cats.

Seizures can result from epilepsy, brain tumors, or other conditions and are more common in middle-aged to older cats.

Vestibular Disease is often sudden onset, affecting balance and coordination, leading to head tilt, circling, and loss of balance.

Lymphoma is one of the most common cancers in cats, often affecting the lymph nodes, intestines, or chest, leading to weight loss, decreased appetite, and sometimes respiratory issues.

Oral Squamous Cell Carcinoma is a common oral cancer in cats, leading to difficulty eating, drooling, and weight loss.

Obesity is common in domestic cats and can lead to related conditions like arthritis, diabetes, and decreased quality of life.

Feline Infectious Peritonitis (FIP) is caused by a mutated feline coronavirus, it leads to immune-mediated inflammation in various organs, causing lethargy, weight loss, and fluid accumulation in the abdomen or chest.

Hemolytic Anemia happens when the immune system attacks red blood cells, leading to anemia and weakness.
