Why Rabbits Are Heat-Vulnerable

Rabbits lack functional sweat glands and rely exclusively on ear vasodilation to dissipate heat. At ambient temperatures above 28°C (82°F), this mechanism is insufficient. Domestic rabbits descended from European wild rabbits that burrow underground — they have zero evolutionary adaptation to high surface temperatures.

Critical Signs of Heat Stroke

  • Rapid, shallow breathing (mouth breathing is a late-stage emergency sign)
  • Wet chin and chest from hypersalivation
  • Lethargy progressing to unresponsiveness
  • Ears hot and red (vasodilation attempt)
  • Seizures in end-stage hyperthermia

Emergency Cooling Protocol

1. Move rabbit to air-conditioned space immediately. 2. Mist ears with room-temperature water — never ice water. 3. Wrap body in a damp (not wet) towel. 4. Offer water via syringe if conscious. 5. Transport to exotic vet. Do NOT submerge in cold water — thermal shock causes peripheral vasoconstriction, trapping heat in the core.

🚨 If Your Pet Has Been Exposed

DO NOT WAIT for symptoms to appear. Contact your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately. Have your pet's weight, the substance involved, estimated amount consumed, and time of ingestion ready. The risk calculator above is an educational estimate only — individual animal responses vary based on age, breed, pre-existing conditions, and concurrent substance ingestion.
