So you've got this fluffy new family member hopping around, and the big question hits you right between the eyes at feeding time. How much food should a rabbit eat a day? I remember staring at my first rabbit, Thumper, holding a scoop of pellets and a handful of hay, completely clueless. I think I gave him a mountain of pellets because, well, that's what the pet store bag seemed to suggest. Big mistake. He got a bit round, and the vet gave me a gentle but firm lecture. It's a question that seems simple but has layers, like a perfectly made salad (which, coincidentally, is part of the answer).
Let's cut through the confusion. The short, oversimplified answer is: a lot of hay, a measured amount of pellets, and a cup of fresh veggies. But if you stop there, you're missing the nuances that make for a truly healthy, happy rabbit. The real answer to "how much food should a rabbit eat a day" depends entirely on your rabbit's weight, age, activity level, and even their health status. A growing baby bunny, a lazy adult lop, and a senior rabbit with dental problems have three completely different dinner plans.
The Absolute Core of It All: Unlimited Timothy Hay
Before we even talk about measuring cups, let's get this non-negotiable point out of the way. Hay isn't just food; it's the engine of your rabbit's entire system. It wears down their constantly growing teeth, keeps their complex digestive tract moving, and provides the essential fiber they desperately need. Asking "how much hay?" is like asking "how much air should my rabbit breathe?"
The answer is: unlimited, 24/7 access. Always. A fresh, generous pile that's bigger than they are. I'm serious. If the hay rack is empty when you go to bed, you didn't put enough in. This is the single most important part of answering "how much food should a rabbit eat a day." The hay portion is infinite.
Not all hay is equal, though. For most adult rabbits, timothy hay or orchard grass hay is the gold standard. It's high in fiber, lower in protein and calcium, which is perfect for maintenance. Alfalfa hay is like candy—rich in protein and calcium—and should only be for young, growing kits under 7 months old or underweight rabbits under a vet's guidance. Giving alfalfa to an adult is a surefire way to cause obesity and urinary sludge.
Pellets: The Concentrated Supplement (Not the Main Course!)
This is where most people, including past me, go wrong. We see the cute pictures on the pellet bag and think that's the staple. Nope. Pellets are a concentrated supplement designed to provide vitamins, minerals, and extra protein that might be missing from a hay-and-veggie diet. They are dense in calories. So, we measure them strictly.
For a standard adult, healthy, non-breeding rabbit, the general rule is about 1/4 cup of plain timothy-based pellets per 5 pounds (2.3 kg) of body weight daily. Let me break that down because it's crucial.
First, you need to know your rabbit's weight. Get a small pet scale. Guessing doesn't work. A Netherlands Dwarf and a Flemish Giant have wildly different needs. Second, the pellets must be high-quality. Look for a pellet where the first ingredient is "timothy hay meal" or something similar, not "corn," "wheat," or colorful seeds and treats mixed in. Those muesli-style mixes are terrible—rabbits pick out the tasty, unhealthy bits and leave the healthy pellets.
I use a plain, boring-looking green pellet from Oxbow or Small Pet Select. Thumper turned his nose up at first after his sugary old brand, but he came around. It's better for him.
| Rabbit Weight | Daily Pellet Amount | Notes |
|---|---|---|
| 2 lbs (0.9 kg) (e.g., Netherland Dwarf) | ~2 tablespoons | Use a measuring spoon, not a guess! |
| 5 lbs (2.3 kg) (e.g., Mini Lop) | 1/4 cup | The standard reference point. |
| 8 lbs (3.6 kg) (e.g., Mini Rex) | ~1/3 cup | Adjust up or down based on body condition. |
| 12+ lbs (5.4+ kg) (e.g., Flemish Giant) | 1/2 cup to 3/4 cup | Larger breeds may need slightly less per pound. |
See? It's not much. If you're pouring a full bowl, you're overfeeding. This strict measurement is a key part of nailing down exactly how much food should a rabbit eat a day. Some owners of healthy, good-eating rabbits even skip pellets entirely with vet approval, relying on a superb variety of veggies and hay. But for most, a small, measured amount is a safe nutritional safety net.
The Fresh Veggie Rainbow: Where Variety Shines
This is the fun part for you and the tastiest part for them. Fresh leafy greens and herbs provide moisture, vitamins, and enrichment. The general guideline is about 1 packed cup of fresh veggies per 2 pounds of body weight daily. Introduce new greens one at a time and in small amounts to avoid upsetting their sensitive stomachs.
Think dark, leafy greens. Romaine lettuce, green leaf lettuce, red leaf lettuce, kale (in moderation due to calcium), arugula, cilantro, parsley, mint, basil, dandelion greens (unsprayed!), carrot tops. Bell peppers (any color) are a great low-sugar option. Carrots? They're high in sugar. Treat them like fruit—a small piece or two as a rare treat, not a daily veggie staple. The same goes for fruit like apple or banana; a tiny thumbnail-sized piece is plenty.
I make a "salad" every evening. A couple of romaine leaves, a sprig of cilantro, a piece of parsley, maybe a slice of bell pepper. Thumper hears the fridge open and comes running. It's our ritual. This cup of greens is a fixed part of his daily intake.
Putting It All Together: A Sample Day for a 5 lb Rabbit
Let's make this concrete. What does the answer to "how much food should a rabbit eat a day" look like in real life for an average-sized bunny?
- Morning: Check hay—top up the pile if it's low. Offer the full daily portion of 1/4 cup of timothy pellets.
- Evening: Check hay again—refill to overflowing. Offer 1 packed cup of fresh, washed leafy greens.
- 24/7: A constant, unlimited supply of fresh timothy hay and fresh, clean water (in a bowl, not a bottle, if possible—they drink more that way).
That's the blueprint. Simple, right? But you have to stick to it. The temptation to give extra pellets "because they look hungry" is strong. Rabbits are foraging animals; they always look hungry. Trust the plan.
Special Cases: When the Daily Rules Bend
The standard guide is just that—a guide. Life happens.
Baby Bunnies (Under 7 months): Flip the script. They need unlimited alfalfa hay (or timothy/alfalfa mix) for growth, unlimited alfalfa-based pellets, and can start introducing veggies slowly around 12 weeks. So for a baby, how much food should a rabbit eat a day is basically "as much as they want" for hay and pellets, focusing on the richer alfalfa.
Senior Rabbits (7+ years): They might struggle with weight loss or dental issues. You may need to increase pellet portion slightly if they're losing weight, or switch to a softer "senior" pellet. Critical Care powder, mixed with water, can become an essential supplemental food. Hay is still king, but you might need to find softer hay types or chop it if they have trouble.
Overweight Rabbits: This is common. Cut back the pellets gradually. Maybe go from 1/4 cup to 2 tablespoons. Increase their veggie variety (low-calorie greens like romaine). But never, ever restrict hay. Encourage movement with toys and exploration.
Underweight/Sick Rabbits: Vet visit first. They may need unlimited pellets, high-fat supplements like Critical Care, and high-quality hay to regain condition.

Answers to the Questions You're Probably Typing Into Google
I've gotten a ton of emails over the years with rabbit questions. Here are the big ones related to daily food.
"Can I free-feed my rabbit pellets?" No. Please don't. It's the fastest way to an obese, unhealthy rabbit with a complete disinterest in their hay. Measured amounts only.
"My rabbit isn't eating all its hay. What do I do?" First, check the hay quality. Is it fresh and sweet-smelling, or dusty and stale? Try a different brand or cut (2nd cut timothy is softer). If they're filling up on pellets first, reduce the pellets. A hungry rabbit will eat hay.
"Is it okay to give treats?" In tiny amounts. A small piece of dried papaya (for enzyme help), a rolled oat, a blueberry. Once a day max. Treats should not be part of the calculated how much food should a rabbit eat a day equation. They're extra.
"How do I know if I'm feeding the right amount?" The poop test. Seriously. Healthy rabbit droppings are round, firm, and fibrous. If they're small, misshapen, or strung together with fur (after the initial reduction from shedding), something's off—usually not enough hay or fiber. Also, body condition. You should be able to feel their ribs with a slight fat covering, not see them, and not have to dig through a thick layer of fat. A defined waist when viewed from above is good.
A Quick Reality Check on Water
I almost forgot this, but it's vital. Food amount means nothing without water. A rabbit needs lots of fresh water to process all that fiber. A heavy ceramic bowl is best. Check it twice a day. If their water intake suddenly drops, it's a vet emergency.
So, there you have it. The long, detailed, hopefully-not-too-overwhelming answer. How much food should a rabbit eat a day? It's a formula: Unlimited hay + Measured pellets (based on weight) + A cup of veggies (based on weight) + Unlimited water.
Stick to that, adjust for life stage, and you'll have a much better chance at avoiding the common pitfalls. It took me a while to get Thumper's diet perfect, and I still tweak it sometimes. But seeing him active, at a healthy weight, and producing perfect little poops is the best reward. It's worth getting right.
Good luck, and give your bunny a head scratch from me.
