Rabbit poop may be black and sticky due to the following 4 reasons:

1. Overnutrition: It may be that the owner only feeds a single rabbit food for a long time, resulting in overnutrition in the rabbit. Rabbit owners need to adjust the rabbit's diet. After adjusting the diet for a period of time, the rabbit's feces will return to normal.

2. Gastrointestinal problems: It may be that rabbits’ gastrointestinal digestive function is not good, and rabbits are greedy, which puts a burden on the gastrointestinal tract. At this time, the pet owner should fast the rabbit for half a day or one day, and then feed the rabbit with an appropriate amount of medicine. If the rabbit does not get better within a few days, other reasons will be considered.

3. Caused by bacteria: It may be that the owner does not regularly clean the environment where the rabbit lives, leading to the breeding of bacteria and infection of the rabbit.

4. Catch a cold: Due to rapid weather changes or large temperature differences between day and night, rabbits have diarrhea. To keep the rabbit warm in time, you can use a blanket or quilt to spread it where the rabbit sleeps.
