How to Choose the Right Pellets for Rabbits

Walk into any pet shop and you’ll see shelves lined with colourful rabbit food bags. Many are marketed as complete diets — but commercial rabbit pellets are actually a small daily supplement to an otherwise hay-based diet, and choosing the wrong product can do real harm over time.

What Role Do Pellets Actually Play?

Pellets were originally developed for commercial rabbit farming to rapidly grow rabbits to slaughter weight. They are calorie-dense and nutritionally concentrated — ideal for rapid growth, but not for the long, healthy life of a pet rabbit.

For pet rabbits, pellets serve a limited but useful purpose: providing a reliable source of essential vitamins and minerals that might otherwise vary in hay-and-vegetable diets. But they should never make up more than about 5% of a rabbit’s total diet by volume, and many rabbit welfare experts note that healthy adults eating high-quality hay and varied fresh greens don’t strictly need pellets at all.

How Much to Feed

The standard recommendation from the House Rabbit Society and RWAF:

• Adult rabbits (7 months – 5 years): ¼ cup (~60ml) of plain pellets per 5 lbs (2.3 kg) of bodyweight per day
• Young rabbits (under 7 months): Unlimited alfalfa-based pellets — kittens need extra calories and calcium for growth
• Senior rabbits (5+ years): Reduce to ⅛ cup per 5 lbs, OR increase if the rabbit is losing weight (senior rabbits often lose weight due to dental changes)

These are maximum amounts. If your rabbit is overweight, reduce pellets further or eliminate them and increase hay and greens instead.

What to Look For on the Label

Good Signs ✓

• Timothy hay or grass hay as the first ingredient — confirming a hay-based formulation
• Crude fibre: 18–25% — the higher the better; fibre drives gut motility and dental wear
• Crude protein: 12–14% — appropriate for adult rabbits
• Crude fat: under 3% — low fat is correct for an adult rabbit
• Plain, uniform pellets — green or brown pellets made from compressed grass

Red Flags ✗

• Seeds, nuts, dried corn, or dried fruit mixed in — “muesli” style foods are one of the most harmful products sold for rabbits. Rabbits selectively eat the sweet, starchy pieces and leave the rest, creating severe nutritional imbalance
• High sugar or molasses in the ingredients list — unnecessary and harmful
• Artificial colours or flavourings — no nutritional benefit
• Alfalfa as the main ingredient (for adult rabbits) — alfalfa-based pellets are too high in calcium and protein for adult rabbits; they’re appropriate for kittens and nursing mothers only

The Problem with Muesli-Style Mixes

Muesli-style rabbit “food” should never be purchased for an adult or juvenile rabbit. Studies found that rabbits fed muesli mixes had significantly higher rates of dental disease, obesity, and gastrointestinal problems, and shorter lifespans compared to those fed plain pellets.

The RWAF has campaigned extensively to have muesli mixes removed from sale, and the UK Government’s Code of Practice for the Welfare of Rabbits specifically recommends against feeding them. If your rabbit currently eats a muesli mix, transition to plain pellets gradually over 2–4 weeks by mixing increasing proportions of plain pellets into the mix.

Pellet Feeding by Life Stage

Baby Rabbits (Under 7 Months)

Feed alfalfa-based pellets in unlimited amounts alongside unlimited hay (hay should be introduced from 3–4 weeks of age). The calcium and protein in alfalfa pellets supports healthy bone and muscle development in growing kits.

Adult Rabbits (7 Months to 5–6 Years)

Transition to timothy-based pellets from 7 months. Reduce the amount steadily until reaching ¼ cup per 5 lbs per day. The diet priority shifts firmly to hay, hay, and more hay.

Senior Rabbits (5+ Years)

Monitor weight closely. Many senior rabbits benefit from slightly increased pellets if they are losing weight (common due to dental changes reducing hay and vegetable consumption). In this case, increase pellets as a calorie supplement and consult your vet.

Do Rabbits Actually Need Pellets?

Strictly speaking — no, provided the diet is otherwise excellent. Wild rabbits live entirely on grasses, herbs, leaves, and bark with no pellets in sight. Domestic rabbits eating unlimited high-quality timothy hay, a wide variety of fresh greens, and occasional foraged herbs can be completely healthy without pellets.

However, pellets provide a practical nutritional “safety net” of vitamins and minerals, particularly for rabbits in smaller homes with limited access to variety. For most pet owners, ¼ cup of good quality plain pellets per day is a reasonable, convenient supplement.

The RabbitCare App

Monitoring your rabbit’s weight monthly is one of the best ways to calibrate pellet portions correctly. The RabbitCare App (free on Android) includes a weight tracking feature where you log monthly weigh-ins and see trends over time — helping you catch weight loss or gain early, before it becomes a serious health problem.
