Yay! Do you know what color? And I actually don't have any experience with indoor rabbits (mine have all been outdoors). I fell like the bedroom would be a better option. With the rabbit in the basement it might be easier to overlook him and she might get lonely. Plus I feel like a lot can go wrong in a basement (temp swings, mold, darkness, etc.). It is slightly on the warm side in your room, but maybe if you keep it closer to 75 she would do better. You could also maybe get her a small fan or something? I would really go with the room if I were you.
I haven't actually seen her yet, haha. I breeder of show quality lops is having to downsize due to medical issues, and she called me asking if I could take this little girl, as she had been raising her to be her next show/breeding rabbit, but wouldn't be able to. Apparently she's a broken tort with a full butterfly. I'm so excited to meet her! And thank you for the advice! I will definitely consider moving it up!
*sigh* There it is again. Does anyone know what that "full butterfly" means? Zip. Nothing. Nada. It has absolutely no significance at all. The breed standard for the Holland Lop calls for "no preference for a butterfly over balanced nose markings" on a broken. It goes on to state that unbalanced nose markings are a fault, not a DQ. When you consider that the standard only allots a whopping 4 points for color, which is to be divided equally between color and markings on a broken, no judge is going to care if the rabbit has a butterfly, so why do so many people seem to think it matters?
Congrats on your soon-to-be bunny - I hope she is all you ever dreamed!
