I'm sure I read somewhere that rabbits shouldn't be given lettuce as its a diuretic (makes them wee a lot!). My Duncan has a small bowl of rabbit mix, although there are pellets available for fussy eaters, and a small amount of veg every morning. During the summer months I cut down on the veg as he is in his run eating grass all day. Fresh drinking water twice a day in hot weather

I would recommend neutering a male rabbit as they can be vicious. Duncan is very docile now he has been "done"
