Our cats are so much more than pets; they're our family. Which is why it can be so troubling when sensitive stomach issues in cats arise. To ensure the comfort and health of your feline friend, it's important to identify and alleviate the symptoms and cause as soon as possible.
Sensitive Stomach Symptoms to Look Out for in Your Cat
When stomach issues arise for your cat, there will be signs. Knowing the key symptoms to look out for is key to catching it as fast as possible.
It's always important when changes occur to rule out a range of health conditions before proceeding with a change of diet or care. Always consult a professional before making a complete diagnosis.
Changes in Behaviour
You know your cat better than anyone, so it's important to consult a veterinarian if you notice a change in personality. Behavioural and mood changes can show up as wanting to hide more, becoming more solitary than usual or becoming increasingly lethargic.
In addition to a change in behaviour, you may also notice a change in appetite. A cat's appetite could become increased or decreased due to sensitivity. So, if your cat starts to act differently around mealtimes, this could be a cause for concern.
Weight Loss
If you notice a change in your cat's weight, it's important to monitor it right away. If you're unsure if your cat's weight management should be a cause for concern, look out for these signs:
- Their ribs are easy to see or feel.
- Their hip and lower back bones are visible.
- You can easily see and feel the spine.
- Cats should have a thin layer of fat covering their bodies, so if this isn't present, it may be a cause for concern.
Whether the weight loss in your cat has been accompanied by a change in appetite will also help you and a professional to determine the cause.
Regurgitation or Vomiting
Vomiting and regurgitation are common symptoms to look out for. If your cat is eating unsuitable food, this may cause vomiting. Unsuitable food can come in the form of human food, which may be too rich and is not designed for cats, or things around the home not meant for consumption. It can also be caused by grass or furballs in the cat's digestive system.
Constipation and Diarrhoea
An additional sign of digestive issues in cats to look out for is changes in their toilet habits. If your cat appears to be struggling to go to the bathroom and only producing a small amount of faeces that is dry and firm, this indicates a digestive issue. Similarly, if they pass any amount of soft and watery stool, this could also be a cause for concern.
Common Triggers That Can Cause Stomach Sensitivity in Cats
Dietary Changes
Cats can be sensitive to changes in diet, so it's important not to make sudden changes to the food they consume. If you’re considering changing your cat’s diet, read our guide on how to change your cat’s food. Cats can also be extremely sensitive to food that is not designed for them. So, while it is tempting to give your loved one little treats from your plate, it is a quick way to cause stomach issues in cats.
Food Quality
The quality of the food your cat eats day in, and day out can have a huge impact on their well-being. Opting for cheap, low-quality food can result in fillers such as corn, wheat and soy. These cheap ingredients offer little nutritional benefits for your cat and can cause gastrointestinal issues.
When choosing a high-quality food for stomach sensitivity, opt for lean proteins such as turkey, chicken or whitefish. These lean meats are easily digestible, while ensuring your cat has enough animal protein needed for muscle maintenance, energy and overall health.
Instead, choose high-quality cat food, made specifically to suit your cat's needs. In addition to the wet cat food and dry food cat food they enjoy for every meal, it's important to take into account treats too. Cats respond well to treats as a reward, and it's a great way to add variety to your cat's diet, without compromising their wellness.
Allergies and Intolerances (includes Dairy)
If your cat is suffering from a sensitivity, intolerance or allergies, this could be causing sensitive stomach issues. Your cat may have a sensitivity to certain proteins, such as beef or fish. In addition to proteins, your cat may also have an intolerance to certain additives, or artificial colours and flavours added to low-end food and treats.
Stress
Another common cause of stomach issues in cats is stress. Common causes of stress in cats can include environmental changes, so if you've recently moved house, keep a close eye on your cat for changes in behaviour that could indicate issues. Another common cause of stress in cats is the addition of a new pet.
While getting a new pet is always an exciting time, during the transition, keep a close eye on both pets for signs of stress and discomfort. Additional stressors like loud noises within the home should be reduced to help keep your cat calm and happy.
Parasites and Infections
Parasites and infections, intestinal worms, bacteria or viruses can cause stomach issues for cats. In the case of parasites and infections, it's important to consult a veterinarian for professional advice.
What are The Best Diets for Sensitive Stomachs in Cats?
Choosing the right diet for your cat's sensitive stomach comes down to a range of factors, including the specific triggers and dietary requirements, as well as the age, breed, and size.
Choose High-Quality Ingredients
If your cat has not been diagnosed by a veterinarian with a specific intolerance or issue, it's a good idea to choose a cat food formula for sensitive stomachs; one that offers high-quality ingredients. In addition to high-quality ingredients, opt for foods that are made with a single protein source, such as lamb or rabbit - not both! Multiple proteins can be harder to digest without adding extra benefits.
It's also a good idea to go for something that is grain-free and gluten-free. This will make the food much easier to digest and gentle on the stomach, while still being nutrient-dense.
Choose Foods High in Omega-3
Choose foods that are high in omega-3 fatty acids, as this can provide significant health benefits for your cat, whether they're suffering from stomach issues or not. Additional omega-3 in your cat's food can improve skin health, improve joint health and mobility, by removing stiffness and discomfort, especially in senior cats that may be suffering from arthritis. In addition to diet, ensure your cat is drinking enough water – as diet and water intake work together to keep your cat healthy.
Does Your Cat Need Hypoallergenic Cat Food?
Another consideration when choosing the best diet for your cat is whether it needs to be hypoallergenic.
How Does Hypoallergenic Cat Food Work?
Hypoallergenic cat food removes a range of common allergens such as wheat, soy and corn - working alongside a veterinarian to provide an elimination diet may help you to determine which key ingredients are causing distress. Elimination diets work by removing certain ingredients and reintroducing them slowly, in order to identify which triggers cause a reaction.
