Frequently asked questions
Why so little pellet food?
Pellets are calorie dense and low in the long fibre rabbits need. Too many cause obesity, dental disease and gut stasis.
Which greens are safe daily?
Romaine, coriander, basil, parsley, kale in moderation and carrot tops. Avoid iceberg lettuce and introduce any new green slowly.
