The reasons why rabbits suddenly stop eating:

1. Not hungry. Rabbits exercise less, digest food more slowly, and don't feel hungry so they don't eat.

2. Pregnancy. If it is a female rabbit, it is very likely that she is pregnant, and hormonal changes have caused a loss of appetite and an unwillingness to eat.

3. Single food. When a rabbit is fed too much food, the rabbit may not eat, which is a sign of anorexia.

4. The weather is too hot. Rabbits are very afraid of heat, and their appetite will decrease significantly after entering summer. In particular, rex rabbits and fur rabbits will hardly eat during the day.

5. Indigestion. When rabbits are managed extensively for a long time or eat a large amount of fermentable feed, they are prone to digestive problems such as gastric accumulation, gastric bloating, weakened gastrointestinal motility, and imbalance of gastrointestinal flora. In this case, the rabbit's feed intake will be significantly reduced. Refusal to eat may even occur.

6. Insufficient drinking water. If a rabbit does not drink enough water for a long time, the lack of water in the body will affect the excretion. The feces will be dry and small or the feces cannot be excreted, and the feed intake will naturally be affected.
