* Water: Rabbits need constant access to fresh water. Without it, they can become dehydrated within a day, leading to serious health issues and even death.
* Food: Rabbits need a diet of hay, fresh vegetables, and a small amount of pellets. They can't survive on just their own stored fat reserves for that long.
* Stress: Being alone and without their usual environment and routine can cause significant stress, leading to health problems.
* Predators: Rabbits are prey animals and are vulnerable to predators, especially outdoors.
It's crucial to ensure your rabbit has constant access to food and water, and that they are kept in a safe and secure environment. If you need to leave your rabbit alone for an extended period, make arrangements for someone to check on them and provide necessary care.
If you're concerned about your rabbit's welfare, it's always best to consult with a veterinarian.
