Polish rabbits are one of the smallest domestic breeds, and their compact size means their nutritional requirements differ meaningfully from larger rabbits. They have a fast metabolism relative to their body weight, so consistent access to high-quality forage is essential. A diet built around unlimited grass hay, a measured portion of pellets, and daily fresh greens will cover the full spectrum of fiber, vitamins, and minerals a Polish rabbit needs.
Fiber is the single most important macronutrient in any rabbit diet, and it plays a dual role for the Polish. First, long-strand fiber from hay keeps the gastrointestinal tract moving properly, preventing the dangerous stasis that small breeds are particularly vulnerable to. Second, the act of chewing hay wears down continuously growing teeth, reducing the risk of malocclusion — a condition that can escalate quickly in a rabbit this small.
Because Polish rabbits weigh so little, even modest overfeeding can lead to obesity. A rabbit carrying excess weight at three pounds faces proportionally greater strain on its joints and organs than a larger breed in the same situation. Portion control on pellets and treats is therefore more critical here than with many other breeds, and owners should weigh pellet servings rather than estimating by volume.
Calcium balance also deserves attention. Rabbits metabolize calcium differently from most mammals, excreting excess calcium through the urinary tract. Too much dietary calcium can lead to bladder sludge or stones, which are painful and sometimes require veterinary intervention. Choosing greens with moderate calcium content and rotating varieties helps keep intake in a healthy range.
