ive had both, bucks smell musky and i needed to change them every day! they were lazy, calm and slept alot. never could get them to use the litter tray.
my does were very active, loved to run around, didnt like cuddles or being held at all. they seemed to wee out towards the wall though? not sure if any one elses do it? oh and they loved poking their poo out the bars
best to stretch your limits and get 3, if one passes the remaining one still has a friend.
