I had a lop previously and currently have a mini rex. They aren’t any more difficult to care for than other small animals in my opinion (hamster, Guinea pig). Yes, the litter/cage needs to be cleaned frequently or it will smell pretty darn awful. Litter and poop will get kicked out of the cage. If you litter train them to go in a box instead of the whole cage the cleaning is easier. They are active at dawn and dusk so keep that in mind. They also need large cages or frequent exercise outside the cage. They chew EVERYTHING. my husband does not like my rabbit because she’s done some damage lol. But they are very sweet and love to cuddle. They like to play with toys and can be social. They’ll come up to you for petting and do big hops in the air when they’re happy. We would put mine in a harness and take outside for walks. Feeding is easy, they eat Timothy hay and pellets, and daily greens will help keep their gut healthy too. FYI, we found out my husband is allergic to hay—not the rabbit itself but the hay they need for digestion. Something maybe to test for before committing.
