The Timothy Hay will come in a bag that is compressed into a bail. The hay is good for the rabbit's digestive system and will keep them healthy. Another store bought food, alfalfa hay, can be purchased in blocks or as hay. This is good to give to your rabbit as a treat, but not as the main food supply. I prefer to give my rabbits the alfalfa in a block, so as to help wear down their teeth.
Rabbits also eat a number of other foods.
My rabbits eats lettuce, carrots, apples and bananas. They also like pears, strawberries, sunflower seeds and a number of other vegetarian food. Fruits and vegetables should be given to yours once a day. Try to vary what you give your rabbits and remember to only let the rabbits eat as much as they want and then take the food out of the cage. If left in the cage it can spoil and the rabbits may get sick.
