Rabbit Diet Guide: Hay, Leafy Greens, Pellets and Treats

A healthy adult rabbit diet is built around grass hay, not bowls of pellets, colorful seed mix or unlimited fruit. High-fiber forage supports both gastrointestinal movement and the continuous chewing rabbits need for dental wear.

Hay is the foundation

Rabbit.org recommends unlimited grass hay as the dominant part of the adult rabbit diet. Timothy, orchard and other suitable grass hays can be offered freely.

Why hay matters

Long-stem fiber supports gut motility and requires prolonged chewing. The House Rabbit Society’s hay guidance also links a forage-rich diet with natural grazing behavior and dental wear.

Leafy greens add variety and moisture

Offer a rotation of rabbit-safe leafy greens and introduce new foods gradually. Sudden large changes can upset digestion.

Pellets should be measured

Plain high-fiber pellets can contribute vitamins and nutrients, but unlimited pellets are calorie-dense and can displace hay. Avoid “gourmet” mixes containing seeds, nuts and colorful cereal pieces.

Treats are genuinely optional

Fruit and carrot are much sweeter than hay and greens. Use tiny portions rather than daily handfuls. Rabbit.org recommends treating extras as a small part of the total diet.

Fresh water always

Provide clean water continuously. Bowls are often easy for rabbits to drink from naturally, though the best setup is the one that remains clean and reliably accessible.

Baby, pregnant and medically complex rabbits differ

Young growing rabbits, nursing mothers, seniors with weight loss and rabbits with kidney or dental disease may need a modified feeding plan. Do not apply an adult-maintenance chart to every rabbit.

Watch droppings and appetite

Changes in fecal size or quantity can be an early warning that intake or gastrointestinal movement has changed. A rabbit that stops eating or producing droppings needs urgent veterinary attention.

Common feeding mistakes

• too many pellets;
• seed/grain mixes;
• large daily fruit portions;
• too little hay;
• abrupt diet changes;
• assuming “rabbit treats” are nutritionally useful.

Choose hay by quality, not by one brand

Good grass hay should smell fresh, be dry and free of visible mold or excessive dust. Some rabbits prefer one grass type over another, so timothy, orchard or other suitable grass hays can be rotated while keeping fiber intake high.

Pellet labels need the same scrutiny as other pet foods

Look for a plain, uniform high-fiber pellet rather than mixes full of colorful pieces, seeds and dried fruit. The rabbit should not be able to selectively eat only the highest-calorie ingredients.

Introduce greens one at a time

When adding a new leafy green, start with a small amount and watch appetite and stool. Introducing several foods at once makes it harder to identify what caused digestive upset.

Fruit should not become a training staple

Small fruit rewards are highly motivating, but frequent pieces add sugar quickly. Use tiny portions or reserve part of the normal pellet ration for routine training.

Dental disease can change eating style

A rabbit that suddenly prefers pellets and soft greens over hay may have mouth pain. Because hay requires prolonged chewing, selective refusal can be an early reason for a dental examination.

Weight changes need context

Obesity can result from too many pellets and treats, while weight loss can indicate dental, gastrointestinal or systemic disease. Weigh rabbits periodically rather than waiting until body change is visually obvious.

Diet changes after illness should follow the veterinary plan

Recovery foods and syringe-feeding products are useful in specific situations, but they are not substitutes for the rabbit’s normal hay-rich diet once normal eating returns.
