Domestic rabbits need sunlight. It is essential for them as they don’t receive as much sunlight as wild rabbits. Sunlight helps rabbits to get the needed vitamin D to develop stronger bones and teeth. 

According to research conducted by the University of Illinois, rabbits need sunlight for absorbing essential vitamin D. Lack of vitamin D can lead to brittle and weak bones and also teeth problems. 

In indoor rabbits, their food cannot always provide the need for vitamin D and calcium. They have to get out in the open to absorb that vitamin D and UV rays. 

For indoor rabbits, most of the vitamin D and UV rays are blocked out by roofs and windows. This is why it is necessary to give your little bunny a frequent stroll in the garden to absorb a little sunlight. 

Some rabbit owners will be reluctant to let their pet rabbit out in the open due to potential predators or the danger of eating something toxic but you have to keep in mind that sunlight is an absolute necessity for your rabbit. 

While taking your rabbit out into the sunlight, you have to be mindful of how much sunlight rabbits need and how long they are supposed to be in the sunlight. Let’s explore more about it in this article.
