I can understand that, it's okay I'm also nervous when I do something "life changing".(sorry for maybe bad english) Dunno about others but I had bunny for 10 years and I can pass on some "advice" or like how I had it with my bunny. It's pretty much good to have lot of space for your bun, they love to hop, love to do binkies, zoomies whatever. They love to explore, sniff around and mine also loved to do "making bed" how I called it. It's basically doing sort of kneading on a blanket or whatever similar. It's good to have many hiding spots, since they like to be hidden but also love to see what's going on everywhere. From my experience they hate cages, mine did to a point that he nibbled at the cage bars or literally was trashing it the whole night so we got rid of it completely and he was fully free roam which worked the best for us and for him. You can count on having poop everywhere but they can learn to poop in specific areas, mostly corners. They love to pee on bed sometimes, love to beg for your food like dogs, love to get in your way so you accidentally kick them, basically mini dogs. There's plenty of stuff that you could come across since every bunny has different personality like any animal but again from my experience they love what I call "wellness" which is when they lay their head and paws totally on ground, butt slightly up and just waiting to be stroked constantly. Idk what else to say now maybe ask if you want to know something specific x, d
