You can't just eat grass. The amount of rabbit food doesn't have to depend on rabbits under 3 months old: alfalfa (one in the morning and one in the evening, rationed)+Timothy (unlimited)+young rabbit food (one in the morning and one in the evening, rationed at 5% of the rabbit's weight every day)+cold boiled water (unlimited).

(For example, if the weight is 600 grams, 600*5%=30 grams, it needs to eat about 30 grams a day, divided into two meals in the morning and evening, and fed once in the morning and evening. At first, you can feed alfalfa less or more, and then you can adjust the amount by observing the poop of rabbits. Timothy and cold boiled water must be supplied in unlimited quantities. Timothy is helpful to promote gastrointestinal peristalsis and incidental molar function in rabbits. If you eat too much alfalfa and keep pulling grapes, stop alfalfa and let Tutu eat Timothy for two days. If Tutu doesn't eat Timothy and is picky about food, the only way is to go hungry. Don't put alfalfa in a cage except ladder grass and cold water. Tutu eats Timothy when he is hungry. )

3-6-month-old rabbits: alfalfa grass (quantitative)+Cynomorium songaricum and western medicine (unlimited)+young rabbit food (5% of body weight)+boiled water (unlimited)

Rabbits over 6 months old: Timoshenko (unlimited)+adult rabbit food (quantitative feeding)+boiled water (unlimited)+appropriate amount of fresh vegetables and fruits.

Go and see more rabbits, study them and feed them scientifically.
