Rabbit care in winter Rabbits will eat more in winter . The extra food also provides them with more fat insulation, but this alone does not keep them warm enough. Their fur coat will also get a bit thicker, but again this only helps them slightly and they'll still rely solely on you to keep them safe and warm! Rabbits do not tolerate extreme weather temperatures so you need to make sure their housing stays warm and comfortable and protects them from the elements. Rabbits do not hibernate, so if your rabbit looks limp or sleepy and isn't really reacting to anything then you need to get him to a vet as soon as possible. If you have just got a rabbit and he's been kept indoors or is a baby, don't put him outside until the weather gets warmer, as the sharp change in weather can kill. Indoor house rabbits should be fine in the cold weather as the temperature indoors tends to be regulated for them! But check that their living area is not in a draught, and if temperatures drop very low during the night you could give them Heat pad (it's like a pet-safe hot water bottle) for some warmth.
