Why Are My Rabbit’s Ears Hot? What to Do

1 Ideal Temperature Range

Rabbits are most comfortable at 18–24°C; young kits prefer a slightly warmer 20–25°C. Once the ambient temperature climbs above 28°C, owners should step in to help their rabbits cool down and avoid heat stress.

During hot summer months, keep a close eye on cooling and heat-prevention measures. Poor ventilation in the hutch, a lack of shade and cooling equipment, or overcrowded housing can all quickly lead to heatstroke.

2 Signs Your Rabbit Is Overheating

When a rabbit gets too warm, its body temperature rises and it becomes far less active, preferring to sprawl out flat on a cool surface. Appetite drops, though this usually improves once the evening cools off. Breathing speeds up and the body may tremble involuntarily. The nose stays moist while the ears turn red and warm. If the ears feel noticeably hotter than usual to the touch, the rabbit is already quite overheated.

3 Preventing and Treating Heatstroke

If a rabbit does develop heatstroke, move it to a shaded, well-ventilated area immediately. Turn on a fan if needed, or apply cold towels or ice packs to the body and head. Swap the cooling material every few minutes to help dissipate body heat faster.

If symptoms don’t improve much, a small amount of blood can be drawn from the ear vein, and glucose or saline solution given by intravenous injection to prevent congestion in the brain and lungs.

You can also give 2–3 drops of a traditional cooling remedy such as Shi Di Shui, or 2–3 Ren Dan pills, taken with a little warm water to ease heatstroke symptoms.

Alternatively, a 20% mannitol or 25% sorbitol injection (10–30 ml per dose) can lower intracranial pressure and relieve heatstroke.

For rabbits showing limb tremors or convulsions, an intramuscular injection of 2.5% chlorpromazine hydrochloride at 0.5–1 ml per kg of body weight can help.
