What should you do if your cat is vomiting or having diarrhea

1. Assess the Severity: Determine how severe the vomiting or diarrhea is. If it's a one-time occurrence and your cat otherwise seems fine, you can monitor them closely. However, if it's persistent, severe, or accompanied by other concerning symptoms, such as lethargy, loss of appetite, or blood in the vomit or stool, seek veterinary attention promptly.

2. Monitor Hydration: Both vomiting and diarrhea can lead to dehydration, so it's crucial to ensure your cat stays hydrated. Offer fresh water frequently, and consider adding a small amount of electrolyte solution (available at pet stores) to help replace lost fluids.

3. Dietary Changes: Temporarily switch your cat to a bland diet to give their digestive system a chance to settle. Offer easily digestible foods such as boiled chicken (no bones or seasoning) or plain cooked rice. Avoid feeding them rich or fatty foods during this time. 

4. Small, Frequent Meals: Instead of feeding your cat large meals, offer small portions of food more frequently throughout the day. This can help ease the strain on their digestive system.

5. Medication: If your vet has prescribed medication for your cat's condition, administer it as directed. Be sure to follow the prescribed dosage and complete the full course of treatment.

6. Isolate the Cat: If you have multiple pets, consider isolating the cat experiencing vomiting or diarrhea to prevent the spread of any potential infections to other animals.
   

7. Cleanliness: Keep your cat's litter box clean and ensure they have access to a clean environment. This can help prevent further gastrointestinal upset.

8. Observe and Record: Keep an eye on your cat's symptoms and behavior, and make note of any changes. This information can be valuable for your vet in determining the underlying cause of the issue.

9. Veterinary Consultation: If your cat's vomiting or diarrhea persists for more than 24 hours, is severe, or is accompanied by other concerning symptoms, consult your veterinarian promptly. They can perform a thorough examination, diagnose the underlying cause, and recommend appropriate treatment. 

Remember, it's always better to err on the side of caution when it comes to your pet's health. If you're ever unsure or concerned about your cat's condition, don't hesitate to seek professional veterinary advice.
