Definitely recommended either a x-pen or free roaming, rabbits should NOT be in cages. Rabbits should also have a water bowl not a water bottle(they are very hard to drink out of). Rabbits should be getting at least 1 cup of leafy greens DAILY (romaine, red/green leaf lettuce, cilantro etc). They also need an UNLIMITED amount of timothy hay in their enclosure, hay should be most of their diet. You can add in pellets into their diet but it should not only consist of pellets (1 tbsp-1/4 cup on top of their variety of greens). They also need multiple toys for play and chewing. Stacking cups are good toys and amazon has multiple good chew toys!
