The 7 Best Weight Gain Foods For Rabbits

Although most rabbits naturally stay at a healthy weight, some extra pounds need to be put on.

BestForPets (bestforpets.org) assumes you've had your rabbit tested for any underlying health problems that might be causing it to lose weight and you're now looking for a good brand to safely gain weight .

These are the brands of rabbit food that customers regularly buy to help their pets gain weight. We'll share our thoughts on each brand, as well as the opinions of our bunnies.

After the review, you will find a brief buyer's guide that discusses those that are helpful in increasing the product and those that are not.

Let's review the best weight gain foods for rabbits in detail, covering topics like nutritional value, fat content, alfalfa content, fiber content, safety, etc.

Instruction Manual

So, let’s talk about what works best to make your bunny fat.


The Rabbit House claims that rabbits have healthy digestive systems and almost never become overweight. You should consult a vet if your rabbit starts losing weight, since this might indicate a serious health issue.


It’s simplest to feed your rabbit pellets, or dry food, to help it gain weight. Due to the high nutritional and caloric content of these meals, we only give our rabbits around 18 to 1/4 cup each day.

Increasing the pellet count will almost always result in a weight gain, but you should be careful to only do it with nutritious food that won’t injure the animal.

You may receive the extra nutrients your adult rabbit needs by feeding it food designed for young rabbits or rabbits about to be used in breeding.

Also, since there will be more nutrients in each pellet, your rabbit won’t have to eat as much to reach an ideal weight, and the food made specifically for young bunnies may be of higher quality.


Alfalfa is a nutritious crop, but it also contains toxic calcium that can cause bladder stones in some rabbits. For best results, consult your vet before feeding alfalfa to a rabbit that has lost weight as a result of bladder stone issues.


Since rabbits’ delicate digestive systems have trouble with the fermentation process that occurs when they consume fruits, we exclusively propose fruits as treats for rabbits.

Constipation, bloating, and uncomfortable gas are just a few of the digestive issues that might arise.

A piece of fruit may be just the thing to get your picky bunny to eat. Fruit is a common food source for rabbits, and in certain situations they may begin eating again.

Adding extra fruit treats to your rabbit’s diet will help them gain weight if they are already eating, but you should keep an eye out for indications of flatulence and other digestive issues.


Oats are a popular food for rabbits and often serve as a gateway food for picky eaters. Also, oats are a quick way to see your rabbit’s weight go up.

Most people avoid them since their rabbits get absolutely little nutritional value from them and instead choose to reward with fruit. Oats are one of 15 foods that might be dangerous to your rabbit, according to PETA.

Feed your rabbit roughly a teaspoon each day in water if it needs to gain weight. Oatmeal can also be used as a vehicle for administering medications or other supplements your rabbit may need.

Dietary Modifications

Repeatedly throughout this brief advice, we have stressed the need of introducing any nutritional changes gradually over the course of many days to avoid upsetting your rabbit’s delicate digestive tract.

While keeping a tight check on your rabbit, gradually increase the number of new things like fruits or oats in its diet until you reach the proper amount.


Increasing your rabbit’s pellets on a regular basis is the best way to help them gain weight. Since rabbits usually get only a modest amount, any increase will cause them to gain weight.

Changing your pet’s diet should be done gradually to allow them to adapt, and only the best quality food should be used. We present Manna Pro Small World Complete Rabbit Meal as a prime example of a high quality food that can increase the weight of your rabbit without adding any unwanted additives or toxins.

An example of cheap hay that can aid weight gain in a natural way is Oxbow Oat Hay Small Animal Food.

If you are looking for the best weight gain foods for rabbits, BestForPets (bestforpets.org) hopes this information will be helpful in narrowing down your options.

Please share this on social media for the top rabbit weight gainers if you think your friends and followers could benefit from knowing this.


In a Nutshell, the Best Rabbit Food Is Manna Pro’s Small World Formula

Our research has shown that the Manna Pro Small World Complete Rabbit Food is the finest option for rabbits looking to gain weight. For regular bowel movements, try this brand’s high-fiber foods.

In the event that your pet’s weight loss is due to an underlying health problem, the abundance of vitamins and minerals in this food will help keep their immune system strong. Corn products and artificial preservatives are not included.

Both our bunnies and us were pleased with the results we got from feeding them Manna Pro Small World Complete Rabbit Food. The only real complaint we have is that the bag was full of dust.


  • Intensely fibrous
  • Absolutely no Corn-Based Ingredients
  • Minerals and vitamins that the body needs


  • Dusty


Highest Quality at the Lowest Price: Oxbow Oat Hay Rabbit Food

We found that Oxbow Oat Hay Small Animal Food was the most cost-effective food for rabbits to put on weight. Oat hay, which is used in this inexpensive meal, is nutritionally equivalent to western timothy hay.

We fed the seed heads of oat grain to our rabbits because of their high fiber content. In addition to being delicious, this meal is fantastic for their teeth since it may help wear them down and wipe the plaque and tartar off of their teeth. It’s multipurpose; you may use it as bedding, as a supplement to your pet’s diet, or both.

Oxbow Oat Hay Small Animal Food was inexpensive and was well-liked by our bunnies. The only real complaint we have is that some of the things we received were much poorer quality than others.


  • Wheat hay
  • Intensely fibrous
  • Effective for oral hygiene


  • Variability in performance


Rabbit Chow Made from Timothy Hay (Mazuru)

When it comes to supplemental rabbit nutrition, we recommend Mazuri’s Timothy-Based Rabbit Food. This brand gives us a comprehensive and balanced diet, so there’s no need to buy any extra vitamins to make sure your rabbit stays healthy.

Probiotics like Lactobacillus and Enterococcus sp. are added to Mazuri’s food to support healthy digestion and the immune system, in addition to the high-quality, pesticide- and preservative-free ingredients.

The Omega-3 fatty acids included in flaxseed oil can improve your pet’s eyesight and make their coat seem lustrous and healthy. The food can be kept fresh for longer and is easier to pour thanks to the resealable bag.

Similar to other healthy products, the disadvantage of Mazuri Timothy-Based Rabbit Food is that it might cause digestive issues in certain rabbits. It won’t taste good to all bunnies. Despite our best efforts, some of the bunnies just refused to eat the meal no matter how we presented it to them.


  • Completely nourishing
  • Probiotics like lactobacilli and e. coli
  • Omega 3


  • Not all rabbits will consume it.


Adult Rabbit Food by Sherwood Pet Health

High-quality vitamins and chelated minerals are used in Sherwood Pet Health Adult Rabbit Food to create a completely nutritionally balanced diet for your rabbit. The grasses and legumes in it promote good digestive and oral health.

Despite promises that Sherwood Pet Health Adult Rabbit Food reduces smells, we found that it actually made our rabbit’s feces smell worse. Alfalfa, another ingredient in this dish, is a calcium powerhouse that can cause bladder stones.

You shouldn’t use this meal to help your baby gain weight if he or her has urinary tract issues.


  • Adequate and healthy sustenance
  • Chelated minerals and vitamin supplements


  • Has alfalfa in it.
  • Strongly odorous garbage


High-Tech Rabbit Chow

The last rabbit food brand we recommend is Science Selective Rabbit Food. Keep your pet healthy and active with the balanced nourishment provided by this brand. 

This blend of high-fiber grasses and alfalfa can help your rabbit gain weight by providing the extra calories it needs.

Unfortunately, the high calcium content of the alfalfa in Science Selective Rabbit Food increases the risk of bladder stones. You should probably look elsewhere for rabbit food if your pet is losing weight due to urinary tract issues.


  • High dietary fiber content
  • Adequate and healthy sustenance


  • Alfalfa


Planting a Wild Harvest Wh-83544 This Rabbit Food From Wild Harvest Has The Latest In Nutritional Technology

The Wh-83544 Wild Harvest In contrast to many of the other options here, the Wild Harvest Advanced Nutrition Diet For Rabbits brand is more like a collection of novelty delights than a staple diet.

This brand is a medley of grains, nuts, and fruits that may be fed to rabbits and other small animals. It’s packed with antioxidants to keep your pet healthy and strong all year round.

It’s a great source of fiber, which is always welcome for maintaining a sound digestive system.

Fruit is a common ingredient in the Wild Harvest Wh-83544 Wild Harvest Advanced Nutrition Diet For Rabbits, which might cause digestive issues in your pet rabbit. Likewise, our pets had a habit of picking through it, eating only the parts they found appealing and discarding the rest.

This sorting produced a great deal of trash, which was exacerbated by the presence of several crumbs in each of the bags we examined.


  • Jar with a hinged lid
  • A gourmet combination of grains, fruits, and nuts.
  • Added with protective antioxidants
  • High dietary fiber content


  • Plenty of fruit in it
  • The pets rummage through it.
  • Huge Amounts of Crumbs
