My Big Guy Wabbit, Maize really loves these Vitakraft Rabbit Slims with Alfalfa! There is a sister product with Carrot. Maize likes both a lot. The crunch seem to be the thing and that he sorta has to nose-wrangle it in front of him. Vitakraft does a good clean product that you can feel good about giving to your Bunny in moderation. These are a pretty big snack and can be broken in half if you like. They are very puffed up, so I don't think they play calorie-wise as big as they look. I'm sure they are excellent for tooth maintenance! I like that at times I can give one and it seems to satisfy Maize for quite a while. It seems to hit him like a 'small meal event' as oppose to a 'snack event'. And Maize keeps Real close track of this sort of thing :)) But Good stuff and it's Maize Approved!
