Is my rabbit eating too much?

Q: My rabbit is looking a wee bit chubby. I was wondering if this is because we are letting him on the lawn to eat grass?
A: Or could it be that you have been feeding him a little bit too much? You would think that the extra exercise in your garden would make him lose weight, and grass is quite low in energy, so his other supplied foods play the major role in his weight gain.
Commercially prepared foods have far greater energy content, so should be used sparingly when supplementing with hay and grass. Just a very small handful is more than enough each day, allowing him to fill up on grass in your garden to keep his weight down and his teeth well worn and healthy.
