Why is My Cat Not Eating or Drinking After Diarrhea? How to Handle It

If your cat is experiencing diarrhea and subsequently refuses to eat or drink, it could stem from indigestion or a gastrointestinal infection caused by bacteria. For kittens that haven't completed their vaccination schedule, feline panleukopenia (cat distemper) should also be considered, requiring immediate veterinary attention for the best chance of survival.

1. Indigestion

Kittens have delicate digestive systems that are not fully developed. Eating too quickly or consuming too much food can lead to indigestion, resulting in diarrhea and a loss of appetite. Sudden changes in cat food can also cause digestive issues. To address this, owners can administer appropriate probiotics to promote gastrointestinal motility. Increasing the kitten's activity level can also aid in digestion.

2. Gastroenteritis

If your cat experiences diarrhea along with vomiting, reduced energy, poor appetite, and an elevated temperature, it may be suffering from gastroenteritis. Given kittens' weaker immune systems, severe diarrhea can cause dehydration and shock. Prompt veterinary care, including intravenous fluid therapy, is crucial to rehydrate your cat and prevent shock.

3. Feline Panleukopenia (Cat Distemper)

Kittens are particularly susceptible to feline panleukopenia, especially those not yet vaccinated. Key symptoms include lethargy, loss of appetite, vomiting, bloody diarrhea with a foul odor, and fever. This is a major infectious disease in kittens. If you notice these symptoms, immediate veterinary care is vital. With aggressive fluid therapy, the cure rate can be as high as 60-70%.

4. Internal Parasites

Kittens with weak immune systems are prone to parasite infections. It's generally recommended to start deworming kittens around 2-3 months of age. If your cat hasn’t been dewormed, infections with parasites like roundworms, tapeworms, coccidia, or hookworms can cause persistent diarrhea and poor appetite. Examine your cat’s stool for visible worms. If found, consult your veterinarian promptly and administer deworming medication according to your cat’s weight and product instructions.
