Many cat owners worry when their feline companions start drinking excessively and vomiting. This is especially concerning in older cats, as it can indicate a range of underlying health issues. While occasional vomiting and increased thirst aren't always cause for alarm, persistent symptoms warrant immediate veterinary attention. This article will explore potential causes for this concerning combination of symptoms in older cats, helping you understand what to look for and when to seek professional help.
Why is my older cat drinking so much water and throwing up?
This symptom combination can stem from several sources, ranging from relatively minor issues to serious medical conditions. The key is to observe your cat closely and document the frequency and severity of both the increased water intake (polydipsia) and vomiting.
Possible Causes:
-
Kidney Disease (Chronic Kidney Disease or CKD): This is a common ailment in older cats. Damaged kidneys struggle to filter waste products efficiently, leading to increased thirst (as the body tries to flush out toxins) and vomiting (due to the buildup of toxins in the bloodstream). CKD often progresses slowly, so early detection is crucial. Symptoms can also include weight loss, lethargy, and changes in urination habits.
-
Diabetes: Diabetes mellitus affects a cat's ability to regulate blood sugar levels. High blood sugar levels can lead to increased thirst and frequent urination, as the body attempts to eliminate excess glucose. Vomiting can also occur due to the metabolic imbalance.
-
Hyperthyroidism: This condition involves an overactive thyroid gland, leading to an accelerated metabolism. Cats with hyperthyroidism often exhibit increased thirst, appetite, and weight loss. Vomiting can also be a symptom.
-
Infections: Urinary tract infections (UTIs), pancreatitis, or other infections can cause both increased water intake and vomiting. Infections often present with additional symptoms like lethargy, fever, or changes in urination/defecation.
-
Gastrointestinal Issues: Inflammation of the stomach or intestines (gastritis or enteritis), inflammatory bowel disease (IBD), or other digestive problems can lead to vomiting and potentially increased thirst as the body tries to compensate for fluid loss.
-
Dental Disease: Painful dental problems can affect a cat's appetite and can indirectly lead to changes in drinking and vomiting habits.
-
Certain Medications: Some medications can have side effects that include increased thirst and vomiting.
What are the symptoms of kidney disease in older cats?
Kidney disease in older cats often presents subtly at first. Symptoms can include increased thirst and urination, weight loss, lethargy, poor appetite, and changes in coat condition. Later stages can involve more severe vomiting, weakness, and even neurological signs. Early detection is crucial for managing CKD effectively.
How is diabetes diagnosed in cats?
Diagnosing diabetes in cats typically involves a blood test to measure blood glucose levels. A glucose tolerance test may also be performed. Veterinarians may also check for ketones in the urine, a byproduct of fat metabolism that can indicate poorly controlled diabetes.
What should I do if my older cat is drinking a lot of water and throwing up?
Don't delay seeking veterinary care. This combination of symptoms requires a professional diagnosis. Your vet will perform a physical exam, possibly blood and urine tests, and possibly other diagnostic tests to determine the underlying cause. Early intervention is key to managing these conditions effectively and improving your cat's quality of life.
When should I take my older cat to the vet?
If you notice a persistent increase in water intake, frequent vomiting, or any other concerning changes in your cat's behavior or health, schedule a veterinary appointment immediately. Don't wait for symptoms to worsen. Early diagnosis and treatment greatly improve the chances of successful management and a better outcome for your feline companion. Even seemingly minor changes can indicate a serious underlying condition.
