Unfortunately many buns like to urinate on soft things like beds. Some buns like to shred soft beds and cushions and pull out the fluffy stuffing. The beds that have worked best for my buns are the little wooden doll beds. I put pieces of vet bed in them, but some buns like to pee on vet beds too.
Rabbits dont need soft places to sleep on, and many rabbits prefer to lounge on hard surfaces. What rabbits really like though is to lounge on elevated “platforms”, such as the tops of boxes or foot stools or a doll bed. Platforms are great vantage points, rabbits like to get an overview over their area. They also like to lounge under chairs or tables (prey animals like protection from dangers from above – this instinct remains in many buns even though their housed safely indoors). So if you are providing your buns with those sorts of things, they will be very happy. There are f ex cute little cat tents that you can put directly on the floor, many buns like those.
The tendency to pee on the soft bun bed could change over your buns’ lifetime.
Bunfluencer web pages don’t give a very accurate representation of life with buns. Buns are messy. Youngish buns like to bunstruct. The more “famous” bunfluencers get a lot of free stuff so they can throw stuff out as soon as there’s the slightest hint of wear, like a pee stain etc.
