Cat Vomiting: Why Is My Cat Vomiting and When Should You See a Vet?

Why’s my cat vomiting and when should I see a vet?

Cat Vomit is one of the most common reasons pet owners visit the veterinarian. If you are wondering why your cat is vomiting, this guide explains the common reasons, warning signs, treatment options and when it’s time to seek veterinary care.

Is Cat Vomiting Normal?
Cats may vomit occasionally due to hairballs or eating too quickly. However, repeated cat vomiting is NOT normal and should NEVER EVER be ignored.

This is because a healthy cat should not vomit too often. If your furball is throwing up more than once or twice within a short period of time and showing other signs of illness, a vet examination is recommended.

Common Causes of Cat Vomiting

Hairballs

This is because cats groom themselves with their small little cutie tongue -so they tend to swallow loose fur. Most of it passes through the digestive tract, but some can build up in the stomach and be vomited.
Signs include:

Gagging or retching
Vomiting a tube-shaped hairball
Normal behavior after vomiting

Treatment options:
Regular brushings or prescription diets especially for long-haired cats can help reduce hairball vomits.

Eating Too Quickly

They may simply eat too fast if you find your cat vomits immediately after eating.
Common reasons include:

Competition with other pets
Large meals
Excitement during feeding
Running around after feeding

Treatment options:
Using a slow-feeder bowl or offering small portions/smaller meals throughout the day can help.

Sudden Diet Change

Changing your kitty’s food too quickly can upset their stomach and lead to vomiting or diarrhea.
Treatment options:
Always transition to a new diet gradually over a week or 10 days by mixing increasing amounts of new food with old food.

Food Allergies or Food Intolerance

Certain proteins or ingredients in food can develop an allergy or food intolerance to some cats.

Symptoms may include:
Recurrent vomiting
Diarrhea
Itchy skin
Ear infection
Weight loss

Treatment options:
Your vet may recommend a prescription or hypoallergenic diet.

Gastroenteritis

Inflammation of the stomach or intestine can result from infections: Viral infections (e.g., Feline Parvo Virus, Bacterial infections, Protozoa, dietary indiscretion, etc.
Symptoms often include:

Vomiting
Diarrhea
Loss of appetite
Lethargy
Mild dehydration

Treatment options:
Depends on the root cause.

Intestinal Blockage

Cats, especially kittens, may swallow objects such as strings, ribbon, hair ties, etc. An intestinal blockage is MEDICAL EMERGENCY.
Seek immediate veterinary care if your kitty:

Vomits repeatedly and directly after ingestion of food
Can’t keep food or water down

Kidney Disease

Additional symptoms may include:

Yellow gums or eyes
Loss of appetite
Fever
Abdominal pain
Lethargy

Treatment options;
Immediate veterinary treatment is ESSENTIAL.

Poisoning

You must be imagining poisoning as if someone poisoned the cat with dangerous deadly chemicals to all living beings. However, that’s not the case… Cats can get poisoned easily by just our household items.
Many common household items are toxic to cats, for example:

Lilies
Human medications
Cleaning products
Insecticides
Chocolate
Essential oil

If you suspect poisoning, seek emergency veterinary care IMMEDIATELY!

When Should You Take a Vomiting Cat to The Vet??
Contact your vet ASAP if your cat:

Vomits multiple times within 24 hours
Can’t keep food or water down
Vomits blood
Appears weak or lethargic
Refuses food for more than 24 hours
Has diarrhea together with vomiting
Has abdominal pain
Has swallowed a foreign object
Is a kitten or senior cat and experiencing repeated vomiting

Early diagnosis often leads to faster treatment and better outcomes!

How Is Cat Vomiting Diagnosed?
Your vet may recommend:

Physical examination
Blood tests
Urine analysis
Fecal examination
X-rays
Ultrasound imaging

These tests help identify the causes so the appropriate treatment can begin.

Treatment for Cat Vomiting
Treatment may include:

Anti – vomiting medication
Fluid therapy for dehydration
Prescription gastrointestinal diets
Parasite treatment
Antibiotics (when appropriate)
Surgery for intestinal blockages

NEVER give your cat human medications unless instructed by your veterinarian, as many are toxic to cats.

Can Cat Vomiting Be Prevented?
Although not every cause can be prevented, you can start reducing the risk by:

Feeding a balanced, high-quality diet
Changing food gradually
Providing regular grooming to minimize hairballs
Feeding smaller meals
Keeping toxic plants and chemicals out of cat’s reach
Prevent access to strings, ribbons and small toys
Schedule regular checkups with Vet Clinic

Trust Your Instincts…. When in doubt, just get your cat checked.
Vomiting is just a symptom, not a disease. A single episode may not be a cause for concern, but repeated vomiting SHOULD NEVER be ignored. Early checkups can help identify the cause before it becomes a more serious health issue.
