Why Is My Cat Throwing Up? Common Causes and When to Worry
As a cat owner, one of the most concerning things you might experience is finding your feline friend vomiting. While occasional vomiting in cats can be normal, it can also be a sign of an underlying health issue. Understanding the reasons behind your cat’s vomiting and knowing when it’s time to seek veterinary help is essential for keeping your cat healthy.
In this guide, we’ll explore the common causes of vomiting in cats, when you should be concerned, and how to manage this issue to keep your cat happy and comfortable.
1. Hairballs: The Most Common Cause
One of the most common reasons cats vomit is due to hairballs. Cats, especially long-haired breeds like Persians or Maine Coons, groom themselves by licking their fur, which can lead to the ingestion of hair. Most of the time, this hair passes through the digestive system without causing issues, but occasionally, it can form a ball that gets stuck in the stomach and needs to be expelled.
Signs of Hairball Vomiting:
• The vomit typically consists of hair and may look like a compact, cylindrical mass.
• The vomiting often occurs after grooming or excessive licking.
• Your cat may also be coughing or hacking as they try to bring up the hairball.
When to Worry:
• If hairballs are frequent or your cat is having trouble expelling them.
• If your cat is showing signs of distress, such as vomiting without producing a hairball or having difficulty breathing.
2. Eating Too Quickly: Upset Stomach from Overeating
Another common cause of vomiting in cats is eating too quickly. Some cats tend to gulp down their food, which can cause their stomach to be overwhelmed and lead to regurgitation.
Signs of Eating Too Quickly:
• Your cat may eat faster than usual and immediately vomit afterward.
• The vomit may consist of undigested food or bile.
When to Worry:
• If vomiting occurs regularly, despite changes to feeding habits (like using a slower feeder bowl).
• If your cat shows signs of lethargy or discomfort after eating, this may indicate a more serious digestive issue.
3. Dietary Changes or Food Sensitivities
Switching your cat’s food too quickly or introducing new treats can cause digestive upset, leading to vomiting. Additionally, some cats may have food sensitivities or allergies that trigger gastrointestinal distress.
Signs of Vomiting from Diet or Sensitivities:
• Vomiting occurs shortly after eating a new food or treat.
• The vomit may be mixed with bile or undigested food.
When to Worry:
• If vomiting persists despite changing their diet back to the original food.
• If your cat shows signs of diarrhea, lethargy, or refusal to eat, indicating a more serious gastrointestinal issue.
4. Gastrointestinal Issues: Inflammatory Bowel Disease or Other Disorders
Inflammatory Bowel Disease (IBD) is a condition where the stomach and intestines become inflamed, leading to chronic vomiting. Other gastrointestinal disorders, such as food intolerance, constipation, or intestinal blockages, can also lead to vomiting.
Signs of GI Issues:
• Frequent vomiting, often accompanied by diarrhea or changes in appetite.
• Your cat may seem lethargic, have a bloated abdomen, or strain while trying to defecate.
When to Worry:
• If vomiting is chronic or your cat’s condition is not improving despite dietary changes.
• If there is blood in the vomit or stool, or if your cat is losing weight rapidly.
5. Toxicity: Poisoning or Ingesting Harmful Substances
Cats are curious creatures and may ingest something harmful, such as a toxic plant, chemicals, or spoiled food. Ingesting these substances can cause vomiting, along with other symptoms like drooling, lethargy, or tremors.
Signs of Toxicity:
• Vomiting along with other signs of distress, like drooling, lethargy, or uncoordinated movements.
• If your cat has access to potential toxins, like certain houseplants (lilies, poinsettias, etc.), chemicals, or human foods.
When to Worry:
• If you suspect your cat has ingested something toxic, call your vet immediately.
• If vomiting is accompanied by other serious symptoms like seizures, difficulty breathing, or sudden lethargy, seek emergency veterinary care.
6. Underlying Health Conditions: Kidney Disease, Hyperthyroidism, or Diabetes
Chronic conditions like kidney disease, hyperthyroidism, and diabetes can cause vomiting as one of their symptoms. These conditions are common in older cats and require prompt medical attention.
Signs of Underlying Health Conditions:
• Vomiting accompanied by weight loss, increased thirst or urination, changes in appetite, or lethargy.
• Your cat may show signs of dehydration, such as dry gums or skin tenting.
When to Worry:
• If vomiting is frequent and is accompanied by other signs of illness, such as weight loss or lethargy.
• If your cat is older and showing signs of chronic illness, it’s crucial to see the vet for further testing.
7. Stress and Anxiety
Cats are sensitive creatures, and changes in their environment or routine can lead to stress or anxiety. Stress-induced vomiting is not uncommon, especially in cats that are highly sensitive or have a nervous temperament.
Signs of Stress-Related Vomiting:
• Vomiting occurs during or after stressful situations, such as a change in the household, travel, or the introduction of new pets.
• You may notice other signs of anxiety, such as hiding, excessive grooming, or changes in behavior.
When to Worry:
• If your cat’s vomiting is accompanied by extreme anxiety or behavioral changes.
• If your cat seems to be vomiting due to ongoing or unresolved stress, seek advice on how to reduce stress and create a more comfortable environment.
When to Call the Vet:
While occasional vomiting in cats can be normal, frequent vomiting or vomiting accompanied by other symptoms is a sign that something may be wrong. It’s important to monitor your cat’s condition and reach out to your vet if:
• Vomiting occurs more than once a week.
• Your cat shows signs of lethargy, changes in appetite, or weight loss.
• There is blood in the vomit or stool.
• Your cat is vomiting excessively after ingesting something harmful.
Always consult your vet if you are concerned about your cat’s health. They can conduct a thorough examination, run tests, and recommend appropriate treatments to ensure your cat’s well-being.
