We give ours a treat in the morning and one in the evening. Too much of anything, even water is bad for you in large amounts, so moderation is the key. To those of you who disagree, here's a quote from Dr Dean Edell--"you can exercise hard and eat right all the time and you'll ad 2 to 5 years to your life, but it will be a boring life". He goes on to suggest moderation in all things rather than abstention. I know my bunnies enjoy them and even look forward to them and we had one live to be a few months shy of 16, so judge for yourself. At walmart, we also get Croissants, healthy bits, and they have an apple treat that looks like a Raviolo. No matter what you do they will grow old and leave, so we just want them to be happy, healthy and have a great life while they are with us.
