Sick cat symptoms – reasons why cats vomit

One of the most common questions that cat owners ask vets is: Why is my cat being sick? Why is it vomiting? The reasons can actually be very different. While some causes are harmless, others may require more attention.

Understand the possible triggers to support your pet's health and avoid illnesses caused by the wrong food, for example.

1. Hairballs: A common culprit

Many cats experience hairballs due to grooming. Ingested hair can accumulate and cause them to vomit. This is especially common in long-haired cats. Regular grooming and a diet that includes fiber to aid digestion can help minimize hairball-related issues.

Our IAMS for Hairball Control is designed to help reduce the formation of hairballs by supporting your cat’s natural digestion.

2. Dietary sensitivities

Cats can have sensitive stomachs, and vomiting may be a reaction to certain ingredients in their food. Unnecessary additives, low-quality fillers, or sudden changes in diet can all lead to gastrointestinal upset.

For this reason, we have created our special IAMS Advanced Nutrition Cat dry food for Sensitive Digestion, which is rich in Turkey. The carefully balanced and easily digestible recipe ensures that even cats with sensitive tummies can enjoy a delicious, healthy, and complete meal

3. Eating too quickly

Sometimes, cats eat too fast and regurgitate their food shortly afterward. If your cat tends to gobble down meals, consider using slow-feeding bowls or feeding smaller portions more frequently.

4. Ingesting foreign objects

Cats are curious creatures and may sometimes eat something they shouldn’t, such as human food, plants, or even small objects. This can upset their digestive system or, in severe cases, cause blockages.

If you suspect your cat has ingested something harmful, contact your vet immediately.

5. Underlying health conditions

If your cat keeps being sick over an extended period, this may indicate a more serious underlying issue, such as kidney disease, pancreatitis, or hyperthyroidism. In such cases, professional veterinary care is essential. A customised diet can support your cat's nutritional needs.

Sick cat symptoms: When to consult a vet

While occasional vomiting may not require immediate action, certain symptoms suggest a more urgent problem. These include:

  • Lethargy and a lack of energy
  • Blood in the vomit or black, tarry vomit
  • Diarrhea or dehydration
  • Loss of appetite or refusal to eat for more than 24 hours
  • Excessive thirst or frequent urination

If your cat exhibits any of these symptoms alongside vomiting, it’s important to consult your veterinarian as soon as possible.

  1. Feed high-quality cat food
  2. Ensure Proper Hydration
