Diarrhea in cats is a common issue that can be concerning for any cat owner. Discovering your feline friend is experiencing loose stools can be distressing and prompt many questions. If you’re asking “Why Does My Cat Have Diarrhea?”, you’re in the right place. This guide will explore the common causes of diarrhea in cats and help you understand when it’s time to seek veterinary advice.
Mild cases of diarrhea can be relatively frequent in cats and are often triggered by minor dietary indiscretions. Perhaps your cat sampled something new that didn’t agree with their digestive system, like table scraps, or maybe you’ve recently transitioned them to a different brand of cat food. These instances can sometimes lead to temporary intestinal upset.
However, it’s important to be aware that diarrhea can also be a symptom of more serious underlying health conditions in cats. Identifying the potential causes is the first step in helping your cat feel better and ensuring their long-term health.
Common Causes of Diarrhea in Cats
There are numerous reasons why your cat might develop diarrhea. Here’s a breakdown of some of the most frequent culprits:
- Dietary Changes: Abrupt changes in your cat’s food, even to a high-quality brand, can upset their digestive balance. Introducing new treats or flavors too quickly can also lead to diarrhea.
- Food Indiscretions: Cats are curious creatures and sometimes eat things they shouldn’t. Consuming garbage, spoiled food, or even rich table scraps can cause digestive upset and diarrhea.
- Parasites: Intestinal parasites such as worms (roundworms, hookworms, whipworms) and protozoa (coccidia, giardia) are common causes of diarrhea in cats, especially kittens and outdoor cats.
- Bacterial Infections: Bacterial overgrowth or infections in the gastrointestinal tract can result in diarrhea. Common bacterial culprits include Salmonella and E. coli.
- Viral Infections: Viruses like feline panleukopenia virus, feline coronavirus, and feline leukemia virus can cause diarrhea, often accompanied by other symptoms.
- Inflammatory Bowel Disease (IBD): IBD is a chronic condition involving inflammation of the digestive tract. It can lead to persistent diarrhea and other gastrointestinal issues.
- Colitis: Inflammation of the colon (large intestine) is known as colitis and can be triggered by stress, parasites, or dietary issues, resulting in diarrhea.
- Pancreatitis: Inflammation of the pancreas, or pancreatitis, can affect digestion and lead to diarrhea, vomiting, and abdominal pain.
- Liver or Kidney Disease: Dysfunction of the liver or kidneys can sometimes manifest as gastrointestinal upset, including diarrhea.
- Hyperthyroidism: An overactive thyroid gland can increase metabolism and sometimes cause diarrhea in cats.
- Stress and Anxiety: Just like humans, cats can experience digestive upset due to stress or anxiety. Changes in the home environment, travel, or loud noises can be triggers.
- Medications: Certain medications, particularly antibiotics, can disrupt the normal gut flora and cause diarrhea as a side effect.
- Toxins and Poisons: Ingesting toxic substances or poisons can severely irritate the digestive system and lead to diarrhea, among other serious symptoms.
- Ingestion of Foreign Objects: If your cat swallows a foreign object like a toy, string, or fabric, it can cause intestinal blockage and diarrhea, often accompanied by straining and vomiting.
- Intestinal Cancer: While less common, intestinal cancer can be a cause of chronic diarrhea in older cats.
When is Cat Diarrhea Serious Enough to See a Vet?
While a single episode of diarrhea might not be alarming if your cat is otherwise behaving normally, it’s crucial to know when diarrhea warrants veterinary attention. Keep a close eye on your cat and consider the following factors:
-
Frequency and Duration: If your cat experiences more than two episodes of diarrhea in a short period, or if the diarrhea persists for more than 24-48 hours, it’s advisable to contact your veterinarian.
-
Other Symptoms: If diarrhea is accompanied by other symptoms, it’s more concerning. Seek veterinary attention immediately if your cat exhibits:
- Vomiting: Diarrhea and vomiting together can quickly lead to dehydration.
- Lethargy or Weakness: A decrease in energy levels or weakness can indicate a more serious underlying issue.
- Blood in Stool: Bright red blood or dark, tarry stools are signs of intestinal bleeding and require prompt veterinary care.
- Lack of Appetite: Refusal to eat or a significant decrease in appetite, especially when combined with diarrhea, is a reason for concern.
- Dehydration: Signs of dehydration include sunken, dry-looking eyes, a dry nose, and dry, sticky gums.
- Straining to Defecate: If your cat is straining to pass stool but only producing small amounts of watery diarrhea, it could indicate a blockage, which is an emergency.
- Unusual Drooling: Excessive drooling can sometimes accompany gastrointestinal upset.
-
Age and Health Status: Kittens, senior cats, and cats with pre-existing health conditions or weakened immune systems are more vulnerable to complications from diarrhea. Seek veterinary advice sooner for these cats.
-
Recurring Diarrhea: Diarrhea that comes and goes over a short period is a red flag and could signal a chronic underlying condition that needs diagnosis and treatment.
If you are concerned about your cat’s diarrhea or notice any of the warning signs mentioned above, don’t hesitate to contact your veterinarian. They can determine the underlying cause of your cat’s diarrhea and recommend the appropriate treatment plan to help your feline companion recover quickly and comfortably.
