Final answer:
In winter, rabbits should eat more food to maintain body warmth and ensure survival due to decreased food availability and increased energy loss.
Step-by-step explanation:
During the colder months, you should adjust your rabbit's food intake because their body will need more energy to maintain warmth.
Unlike in the warmer seasons, in winter, the availability of food decreases and rabbits need to have a certain threshold level of energy stored in the form of fat.
This energy storage is crucial for their survival in the cold. As more energy is lost by the body in colder weather, rabbits should eat more to maintain a constant weight.
The extra intake of food also helps in accumulating more fat, which serves as insulation against the cold and thus, reduces energy loss from the body.
