How Can I Tell How Big My Rabbit Will Get?

If you have a young rabbit, you might wonder how big they will get when they reach adulthood. The most reliable way to tell how big your rabbit will get is by researching their breed. The table from earlier will give you an idea of the average weight your rabbit might reach. 

If you adopt or rescue a rabbit, you may not have a lot of information about them. If you are unsure what breed your rabbit is, you may be able to work it out by doing some research online. Your vet should also be able to give you some guidance. 

If you know your rabbit’s age, you also use this to estimate their adult size. When a rabbit is around 4 months old, they’ll be about half the size they will be as an adult. When they’re about 6 or 7 months old, they’ll be about two-thirds of their adult size, so don’t have much more growing to go. While this isn’t exact, it’s a good way to get an estimate.

Knowing how big your rabbit will get is important because you need to ensure they have a large enough enclosure to accommodate them when they reach their adult weight. Most pet shop cages and hutches aren’t large enough for a rabbit to live happily. They need plenty of space to stretch out, move around, and play.

How to Weigh Your Rabbit

Since we’re talking a lot about rabbits’ weight in relation to their breed and adult size, you are likely wondering how to weigh your rabbit. The best way to get an accurate weight for your bunny is to take them to your vet to get weighed.

Your vet will have specialist scales and can weigh your rabbit accurately. They can also let you know whether your rabbit is at a suitable weight for their breed and perform a health check. 

If you want to weigh your rabbit at home, you could use simple home scales to weigh yourself. Then simply stand on the scales holding your rabbit and note the weight of the two of you. Subtract your weight, and you’ll be left with your rabbit’s weight. 

Dr. Amir Maurer from the Companion and Exotic Animal Veterinary Center in Holon, Israel, explains that you can also use kitchen scales with a plastic basket or container on top to hold your rabbit. Of course, this depends on the size of your bunny. Since rabbits will move around a lot, weighing them three times and then working out an average is essential.

How Long Does It Take for a Rabbit to Fully Grow?

Rabbits reach their full adult size by the time they’re a year to 18 months old. They won’t continue to grow after this point, so if you notice they’re gaining weight after this time it’s important to take your rabbit to visit the vet.

Rabbits need to maintain a balanced weight to stay healthy, and they may be overweight. Your vet will be able to check and give you advice on whether you need to change your rabbit’s diet

Keeping Your Rabbit at a Balanced Weight

Ensuring your rabbit maintains an appropriate weight is key to ensuring they’re healthy. Rabbits who are overweight are at risk for a number of health issues. The correct diet and plenty of exercise will ensure your rabbit stays healthy. 

Diet

Providing your rabbit with a healthy diet is crucial. Vet Anna Meredith says that feeding a rabbit the correct diet is the most important factor in keeping them healthy. 

Your rabbit should have access to plenty of high-quality hay, some vegetables, and a small number of complete rabbit pellets each day. It’s important not to overfeed and to avoid ‘mixes’, as your rabbit will likely pick out their favorite parts and leave the rest. This means their diet isn’t balanced. 

You should always do your research to ensure any vegetables you feed your rabbit are safe and healthy for them. Check out our detailed guide on what you should feed your rabbit. 

Exercise 

Just like humans, rabbits need exercise to stay healthy.  Ensure your rabbit has plenty of room in their living area to move around. They should also have time out of their enclosure each day with as much space as possible to run around and play. 

You can encourage movement by providing toys and games to keep them interested, as well as by interacting with them. This is also really important for their mental health. Happy rabbits are likely to eat and move around more!

Keep in mind that rabbits are crepuscular, which means they’re awake mostly at dawn and dusk. Offering plenty of stimulation during these times when they would naturally be more active can encourage more movement. 

How to Choose the Right Rabbit Breed for You?

Choosing the right rabbit breed for you can be a daunting task, but it is important to make sure you choose the right one for your lifestyle and living situation. Here are some factors to consider when choosing a rabbit breed:

  • Size: Determine how much space you have available for your rabbit and choose a breed suitable for your living conditions. A small or medium-sized breed may be the best option if you have a small apartment.
  • Temperament: Consider the temperament of the breed you are interested in. If you have children or other pets, you may want to choose a species known for being friendly and sociable.
  • Coat Type: Decide whether you want a rabbit with short or long hair. Breeds with long hair require more grooming and maintenance.
  • Purpose: Think about what you want your rabbit for. Do you want a companion, a show rabbit, or a rabbit for breeding? Different breeds have different purposes and characteristics.
