Claims
*[Paraphrased derived summary — non-Open-Access source.]* Rabbits are heat-sensitive; hot, humid conditions or poor ventilation (in hutches or during transport) can kill many rabbits, especially pregnant does. They need free access to cool water, and when controllable the optimum is 50–70°F (15.5–21°C), 40–60% relative humidity, and 10–20 air changes/hour. *[Paraphrased derived summary — non-Open-Access source.]* Rabbits drink significantly more from a bowl than from a cage bottle; research shows bowl water intake is markedly higher.
