I certainly wouldnt let the rabbit directly bite the food I was eating, and then I eat the rest....but i do break off a piece of any fruit/veg I'm eating and give it to them. Otherwise, they just pester me, because they know I've got it.
One day I spent fifteen minutes lying on my back, with sorrel on my neck/throat, holding a nectarine in the air, because she had smelt it and raced up my front:shock:
*but* the otehr day sorrel pulled down a loaf of bread and took a couple of bites from the crust, I put it back in the breadbin meaning to trim that bit off when I'd put her upstairs, but my housemate ate it before I got the chance
