Veterinary Disclaimer
This calculator is for informational purposes only and does not substitute professional veterinary advice. Rabbit nutritional requirements vary based on individual health, dental condition, gastrointestinal history, and underlying medical conditions. GI stasis is a life-threatening condition in rabbits — always ensure unlimited access to hay and consult a rabbit-savvy exotic animal veterinarian immediately if your rabbit stops eating. The House Rabbit Society (rabbit.org) is an excellent resource for additional guidance.
| Age | Hay Type |
|---|---|
| 0–3 months | Alfalfa (unlimited) |
| 3–6 months | Alfalfa + Timothy mix |
| 6–12 months | Transition to Timothy |
| 1–5 years | Timothy (unlimited) |
| 5+ years | Timothy + more pellets |
Hay first, always: 80–85% of a rabbit’s diet must be hay. It provides essential fiber to prevent GI stasis and naturally wears down teeth.
GI stasis danger: If your rabbit stops eating or pooping for 12+ hours, this is an emergency — contact a vet immediately.
Water matters: Change water daily. Rabbits refuse stale water, which quickly leads to dehydration.
Gradual changes: Always introduce new foods over 7–10 days to avoid GI upset. Never abruptly change a rabbit’s diet.
