Rabbit tails come in all sorts of sizes. Some may be extra fluffy, and others extremely long and straight, but how do you know if your rabbit's tail length is normal? Here are some guidelines to find out if your pet bunny has an average tail length or is too long or too short.

How long is an average bunny's tail?

The answer to how long your rabbit's tail should depend on its breed and genetics. Generally, you should expect around two inches (5 cm) of a fluffy, wool-like ball on the end of your bunny's backside.

Uses of Rabbit tail

1.  Tail provides balance

The rabbit tail length provides balance for rabbits who spend most of their time hopping about instead of walking upright. Without this balancing aid, rabbits would have trouble moving quickly. 

2. Keep the bunny warm

If you have a short-haired bunny, his fluffy tail will keep him warm during the winter months. If you have a longhaired rabbit, his long fur will also act as insulation against extreme temperatures.

3. Communicate

Rabbits communicate via their tails as well. A rabbit that is feeling fearful may curl up and point his tail away from what frightens him, while a more confident bunny will point his rear towards whatever he feels threatened by. The fluffier the tail, the more agitated your bunny's emotions might be at that moment in time. In case of danger, the rabbit will generally use the tail to warn off any predator by waving it around.

Are rabbit tails different?

Yes, they are. Several factors affect the size of a rabbit's tail. These include;

1. Breed

There are many types of rabbit breeds in existence, and they come in all different sizes. The type of breed your bunny belongs to will determine how big their tail is going to grow. 

2. Genetic disposition

Rabbits inherit their parents' genes. This means that if your rabbit had short parents, they would probably have a short tail, too. But if your furry friend's parents were tall with long tails, then they're likely to have a longer one themselves. 

3. Diet

The difference in tail lengths doesn't just depend on the parent's genetic makeup and breed and diet. A healthy diet will make for a healthier bunny, which means bigger, fluffier tails. For example, food can dictate whether or not it grows to be thicker and fuller than usual. That being said, a well-fed bunny will always have a better chance at having a more substantial tail than one whose diet consists mainly of carrots and hay.


A bunny's tail length is largely determined by their genetic makeup and breed, so take a look at yours to see if they match these general rules. Remember that there are exceptions to every rule, and many factors determine whether a particular tail length is normal. You'll need to consult with your veterinarian if you're unsure.
