Can Rabbits Live Without Hay?(Not Really)

Rabbits are known for eating grass and hay, but they eat lots of other things too. That might lead you to wonder, can a rabbit live without hay?

Rabbits need to be eating hay or grass, and this should make up most of their diets. If your rabbit does not get enough of one of these two foods, it will not be able to digest anything properly, so it is important to ensure your bunny gets plenty of hay.

Today we will talk in detail about the importance of hay in your rabbit’s diet.

Do Rabbits Really Need Hay?

Yes, rabbits really do need hay. Hay must be the bulk of their food on a daily basis unless they are getting a lot of grass. Most people don’t have the capacity to feed their rabbits on large quantities of grass, so hay is the most viable option for many rabbit owners.

Rabbits depend upon hay, and you shouldn’t be giving your rabbit much of any other food. Vegetables are good for your bunny too, but only in small quantities. You should never be feeding it large amounts of vegetables, pellets, or any other foods – it needs to get most of its nutrients from hay.

Why Is Hay So Important For Rabbits?

Hay is important because rabbits evolved to eat grass, and it performs a variety of crucial functions. These include:

  • Wearing down the rabbit’s teeth so that they don’t grow into the rabbit’s lips
  • Providing plenty of fiber, which keeps the digestive tract moving
  • Keeping the rabbit engaged and entertained
  • Providing everyday nutrition that the rabbit needs

Without hay, rabbits are at risk of many problems. They can suffer from overgrown teeth, stomach and digestive problems, and boredom. They may also become malnourished because grass and hay provide almost everything that they need.

If they aren’t given access to these foods, they may become sick.

How Often Should Rabbits Eat Hay?

A rabbit should be eating hay every day, as the bulk of its diet. You should make sure that hay is available at all times, and not just fed occasionally.

Rabbits are grazers, and they will have a little nibble of hay, followed by a little nibble of something else, and then a bit more hay. This is good for their digestive systems because it ensures that a constant source of fiber is being added to their stomachs, rather than a lot all at once.

Rabbits should essentially be eating hay all the time. They will have breaks, of course, but on the whole, you will see them eating their hay very frequently.

This reflects how they evolved; rabbits in fields are almost always grazing the grass, hopping to a new patch, and grazing it a bit more. Make sure you provide plenty of hay for your rabbits to browse on so they can eat small quantities whenever they feel like it.

Don’t only give them hay at feeding time and then take it away. It is much better for rabbits to have constant access to this food source.

What Happens If A Rabbit Has No Hay?

Rabbits that don’t have access to either hay or grass can get very ill. They may struggle to get the nutrients that they need from other food sources and might become overweight or underweight, depending on what else you feed them.

Teeth problems

Their teeth will also grow very long, as rodent teeth do not stop growing the way that the teeth of other mammals do. If rabbits aren’t constantly grinding their teeth down on something fibrous, their teeth will grow into their lips and mouths.

This is very painful for the bunny and can cause open wounds.


Your rabbit may also get bored and restless because it won’t be able to undertake its natural behavior of browsing. It might become lethargic or even aggressive, showing signs of unhappiness.

Digestive issues

Furthermore, you may notice digestive issues occurring. Rabbits can suffer from something known as GI stasis, or Gastrointestinal stasis. This occurs when food is not being pushed through the rabbit’s gut because the rabbit isn’t eating the right fibrous foods.

This can cause blockages which can be very painful for the rabbit. The food may become impacted, blocking up the guts, or it may start to ferment, causing gas buildup. All of this is very uncomfortable and can be fatal.

The first signs of GI stasis are a lack of droppings and a disinterest in food. If this occurs, take your rabbit to a vet immediately, because this issue can cause a quick death.

How Long Can Rabbits Live Without Hay?

This depends heavily on what else the rabbit is eating. If it has access to other fibrous foods or grass, it may be fine. If it is not getting enough fiber, an issue like GI stasis could occur.

Even twelve hours without hay can be very bad for your bunny. If you feed your bunny lots of other fibrous foods, it might continue to live for years, but it may be unhappy and unwell.

Always have backup hay on hand when you keep rabbits. You should never allow yourself to run out; have an emergency supply kept somewhere just in case.

What Can Replace Hay For Rabbits?

The only real replacement for hay is grass because it provides the same fiber, and superior vitamins and nutrients. If you cannot get hay for your rabbit for some reason, find a spot where you can gather lots of grass for it.

Pellets, vegetables, fruits, and other kinds of greenery are not a viable replacement for hay, and there really is no other option besides grass. If you are worried about not being able to provide your rabbit with enough hay, stock up, get a friend to store some for you, or make sure you can access lots of grass.

Rabbits can only live without hay if they can eat a lot of grass instead. Hay and/or grass are an essential part of the rabbit’s diet, and there are no alternatives to them. You must give your rabbit one or the other at all times.
