At 7 weeks old, rabbit kits are usually transitioning from a primarily milk-based diet to solid foods. It's important to provide them with a balanced diet to support their growth and development. Here are some suitable foods for 7-week-old rabbit kits:

1. Hay: Offer unlimited access to fresh, high-quality hay, such as Timothy hay or grass hay. Hay is essential for proper digestion, dental health, and providing fiber in their diet.

2. Fresh vegetables: Introduce small amounts of fresh vegetables gradually. Suitable options include dark leafy greens like romaine lettuce, spinach, and kale. Offer a variety of vegetables to ensure a diverse nutrient intake.

3. Pellets: Provide a small amount of high-quality rabbit pellets formulated specifically for young rabbits. Look for pellets with a high fiber content and limited additives. Follow the recommended feeding guidelines on the pellet packaging.

4. Water: Make sure clean, fresh water is available to the kits at all times. Use a water bottle or a shallow dish that they can easily access.

It's important to introduce new foods slowly and observe the kits for any signs of digestive upset. Gradually increase the amount of solid food while reducing the amount of milk they receive from the mother.

Avoid feeding them foods that are high in sugar, such as fruits, as rabbits have sensitive digestive systems and can develop issues like diarrhea if their diet is unbalanced.

Consulting with a veterinarian who specializes in rabbit care can provide you with personalized recommendations based on your specific rabbit breed and circumstances.
