Female rabbits (does) can become pregnant when they are 12 weeks old and can continue to have babies up to the age of four years.
Adult rabbits: 18 months – 7 years. As your rabbit reaches their adult years, they will calm down a little and settle into their own personality. You and your rabbit will start to know each other better and trust each other more. It's the time when your rabbit settles down to be a part of the family.
Hormonal aggression
Hormones can play a factor in aggressive rabbits, particularly female rabbits. Such aggression is usually apparent at sexual maturity (between 3-6 months of age depending on breed) and may occur in territorial situations or be linked to sexual behaviour.
Small breeds (such as the Polish) can be bred at 4 to 5 months of age. Medium breeds (for example New Zealands and Californians) become sexually mature at 6 to 7 months of age. The giant breeds (such as the Flemish Giant) should be at least 7 months of age when bred.
Baby rabbits leave the nest when they're 3 weeks old and about the size of a chipmunk. If you find a chipmunk-sized but fully-furred rabbit with eyes open, ears erect and the ability to hop, they are meant to be on their own. As small and helpless as they may look, they are not an orphan and don't need your help.
Rabbits, just like other domesticated animals, have an average lifespan which can help an owner keep their bunny in optimum health in every stage of life. Unlike their wild relatives, who live for an average of one to two years, domesticated rabbits can live between eight to 12 years.
Caring for your pet rabbit
It is important that you understand all the requirements for caring for a rabbit before you buy one. Rabbits generally live for 5 to 8 years depending on their environment and breed, but they can live for as long as 12 years.
The female rabbit is called a doe, giving birth is called kindling and baby rabbits are called kittens. Rabbit kits are born with their eyes and ears sealed shut, and completely furless.
Newborn hares, called leverets, are fully developed at birth—furred with open eyes—while newborn rabbits, called kittens or kits, are born undeveloped, with closed eyes, no fur, and an inability to regulate their own temperature, Stott said.
Only 20 percent to 25 percent live for a year after birth. That means many rabbits never produce offspring of their own.
They may hump other animals, people, or even objects such as furniture. If this occurs, try to engage your rabbit in another activity, such as some exploration time, a food puzzle, or some rewards-based training. Spaying will resolve this behaviour.
Rabbits just LOVE company!
Most owners house a pair of rabbits, but keeping three or four are also popular options. Be sure that you have enough space to comfortably house all your rabbits, or else you'll have to purchase multiple runs to create enough space.
Breeding rabbits
The female rabbit (doe) does not come into heat (oestrus) as do other animals. The doe will accept the male (buck) at any time of the year. Does are mature and can breed at 5 to 6 months of age and can continue to have young for 4 years.
Having two bonded rabbits can provide them with years of joy and fun. First, you'll want to make sure that both rabbits are spayed/ neutered prior to bonding as it will make the process easier. While female – male bonding tends to be easier, you can certainly bond two females or two males together.
Bunnies show affection by grooming, so if your rabbits gently nuzzle, lick, and perhaps even try to nibble you gently, they are showing you that they love and care for you. This is also a sign of submission. Sometimes your bunny will lick and nibble your clothing or a piece of nearby fabric instead of you.
It is recommended however, that not more than one mating be performed per day for each male as usually, the second ejaculation often contains much more sperm. It is also important to observe a time delay of one day between two mating acts.
Rabbits are capable of a wide range of emotions including jealousy, anger, fear, grief, love, irritability and insecurity.
Grunting: Grunting noises are angry reactions towards another rabbit or a person and should be heeded as a warning to back off; otherwise the rabbit might escalate by scratching or biting. Rabbits grunt when they feel threatened or territorial. Thumping: Thumping is an attention getting behavior.
