aarrgh fat rabbit help

my rabbit has got big:shock:, he was neutured a few months ago and I have just noticed he is putting on weight, i did put another thread on the diet bit about putting their pellets in food balls so they have to work for them and also I will cut down his pellets although they only have a handfull each now but he lives with his wifey bun so how do I make sure he dosen nick hers, its not practical for me to stand and watch them, she is definatly the boss of the marrage lol so i am sure she will stand her ground.
also how do I encourage weigth loss, they have free range of our garden all the day light hours and have things like card board tubes in the hutch and run to play with.
they eat roughly 1 hand ful each of pellets a day, a cabbage leaf each or a carrot each or small amounts of other veg and as much hay as they like

its verry hard to cut back on one bun without effcting the other, i would probably suggest rabbit jumping or any other type of exercise like free ranging, also its quite natural for the rabz to put on a bit of winter weight to keep them warm so just bair that in mind

have a look at the burges exel website i thought they were very informative

How much carrot? Carrot is full of sugar so I imagine that would help pile on some weight

My pair have a handful of pellets between them and I just scatter feed. Don't worry about it, as long as they eat plenty of hay and always have access to hay they won't go hungry
