If your kitten has diarrhea, its important to first consult with your veterinarian to determine the underlying cause and appropriate treatment. However, there are some things you can try at home to help alleviate your kittens discomfort and potentially resolve the issue. Here are some tips on what to feed a kitten with diarrhea:

1. Bland Diet: Feeding a bland diet can help soothe your kittens digestive system. Some good options include boiled chicken and white rice, boiled turkey and pumpkin, or plain boiled rice.

2. Wet Food: Wet food can be easier for kittens to digest than dry food, but its important to choose a high-quality, low-fat, and low-fiber option. Some recommended brands include Smalls Human-Grade Fresh Pulled Bird Recipe, Royal Canin Mother & Babycat Ultra-Soft Mousse in Sauce, Wellness Complete Health Kitten Whitefish & Tuna Cat Food, and Blue Buffalo Basics LID Kitten Turkey & Potato Wet Cat Food.

3. Probiotics: Probiotics can help restore the balance of good bacteria in your kittens gut and reduce diarrhea. Consult with your veterinarian for dosage recommendations.

4. Hydration: Make sure your kitten stays hydrated by providing plenty of fresh water. You can also give them rice water, chicken broth, or plain water to aid digestion and relieve bloating.

Its important to note that if your kittens diarrhea is combined with other symptoms like blood in their stools, loss of appetite, vomiting, rancid-smelling breath, a fever, or dehydration, you should contact your vet immediately.
