Why Is My Cat Throwing Up? A Guide for Concerned Cat Parents

Vomiting in cats can be alarming — and messy. Whether it’s a one-time incident or a recurring problem, understanding the why behind your cat’s upset stomach can help you respond quickly and appropriately. In this post, we’ll walk you through the most common causes of cat vomiting, what different vomit types and colors may indicate, and when it’s time to call the vet.

Is It Normal for Cats to Throw Up?

Occasional vomiting — especially hairballs — can be perfectly normal, particularly in long-haired breeds like Ragdolls. However, if your cat vomits frequently, seems lethargic, loses weight, or stops eating, it’s time to investigate further. As Dr. Lori Teller, associate professor at Texas A&M College of Veterinary Medicine notes, cats who vomit now and then but remain otherwise healthy are generally not a cause for concern. It’s the pattern, frequency, and accompanying symptoms that matter most.

Common Reasons Cats Throw Up

1. Hairballs

Cats groom themselves constantly, and swallowed fur can build up in the stomach. Hairballs are typically coughed up with a gagging sound and may appear as a slimy, sausage-shaped wad of fur. Long-haired cats like Ragdolls are more prone to hairballs, making regular brushing especially important.

2. Eating Too Fast

Some cats scarf their food, which leads to regurgitation — undigested food that usually comes back up within 15–30 minutes of eating. A slow-feeder bowl can make a significant difference for these cats.

3. Dietary Intolerance or Food Sensitivity

Switching foods too quickly, or feeding ingredients your cat can’t tolerate, can trigger vomiting. Common culprits include dairy, certain proteins, grains, or artificial additives. When transitioning foods, always do it gradually over 7–10 days.

4. Ingesting a Foreign Object

Rubber bands, string, plastic pieces, or even certain houseplants can trigger vomiting — and may cause a dangerous intestinal blockage. If you suspect your cat swallowed something they shouldn’t have, contact your vet immediately. Do not wait to see if it passes on its own.

5. Parasites, Infections, or Underlying Illness

Vomiting can also be a symptom of a more serious underlying condition, including:

• Intestinal parasites
• Bacterial or viral infections
• Kidney or liver disease
• Hyperthyroidism
• Diabetes
• Cancer

A vet visit is essential if vomiting is accompanied by lethargy, weight loss, diarrhea, or behavior changes.

What Does the Color of Cat Vomit Mean?

The color and texture of your cat’s vomit can offer helpful clues about the cause:

Vomit Color	Possible Cause
Brown	Hairball, digested food, or possible internal bleeding
Yellow or Green	Bile from an empty stomach
Red or Pink	Blood in vomit — potential emergency, call vet immediately
Black or Tarry	Internal bleeding or toxin ingestion — emergency
Orange or Light Brown	Undigested food, often from eating too fast
White Foam	Empty stomach, stress, or acid reflux

According to the UC Davis School of Veterinary Medicine, blood in vomit or stool should always be treated as a medical emergency.

Vomiting vs. Regurgitation vs. Coughing: What’s the Difference?

Cats sometimes cough, regurgitate, or have hairball episodes that look like vomiting — but aren’t. Understanding the difference helps you give your vet a more accurate picture:

Behavior	Key Signs	Common Causes
Vomiting	Active heaving, retching; can happen anytime	Hairballs, food intolerance, illness
Regurgitation	Passive, no retching; usually right after eating	Eating too fast, esophageal issues
Coughing	Hacking sound, expels air not food	Asthma, respiratory infections, irritants

When to Call the Vet

Contact your veterinarian if your cat:

• Vomits more than 1–2 times per week
• Has blood in their vomit (any amount)
• Shows signs of pain, distress, or bloating
• Isn’t eating or drinking
• Seems lethargic or unusually weak
• Has concurrent diarrhea or constipation

Helpful tip: If you’re unsure what you’re observing, record a short video to show your vet. Seeing the behavior in action can be invaluable for diagnosis.

At-Home Tips to Reduce Vomiting

• Switch foods gradually — always transition over 7–10 days
• Use a slow-feeder bowl to prevent scarfing
• Brush your cat regularly to reduce hairball formation (especially important for Ragdolls)
• Remove hazards — keep toxic plants, string, rubber bands, and small objects out of reach
• Add hairball control fiber supplements or treats to your cat’s routine if hairballs are frequent

A Note for Ragdoll Owners

Ragdolls’ semi-long, silky coats mean they’re more likely to ingest fur during grooming than short-haired breeds. Establishing a regular grooming routine — even just a few minutes of brushing a few times a week — can significantly reduce hairball-related vomiting. We recommend starting this habit early when your kitten first comes home.
