Rabbit collapsed in the heat
Rabbits suffer heatstroke easily — sustained temperatures above the low-to-mid 20s°C are dangerous. A rabbit that is flat out, breathing hard or with an open mouth, drooling, or unresponsive in warm conditions is a medical emergency. Move it to a cool, shaded place and call a rabbit-savvy vet immediately. Cool gradually; never plunge a rabbit into cold or iced water, which causes shock.
Fast answer for owners
- Go now if: Lying flat, weak, or unresponsive in warm conditions; Fast or open-mouth breathing, drooling; Very warm ears, congestion, or convulsions.

What your vet may check
Your vet may check core temperature, hydration, and circulation, and provide controlled cooling, fluids, and supportive care. Heatstroke can cause organ damage that needs monitoring.
Recovery support after veterinary assessment
After emergency care, your vet may advise hydration and gentle daily support, including WOOLY Balance Water and daily-care items, to support recovery — on veterinary advice once your rabbit is stable.
Frequently asked questions
At what temperature do rabbits get heatstroke?
Rabbits are comfortable in cool conditions and struggle as temperatures climb into the mid-20s°C and above, especially with humidity. Treat any collapse in warm weather as heatstroke until a vet says otherwise.
How should I cool an overheating rabbit?
Move it to shade or air conditioning, offer (don't force) cool water, and dampen the ears with cool — not iced — water while you call a vet. Cool gradually to avoid shock.
My rabbit seemed to recover after cooling — do I still need a vet?
Yes. Heatstroke can cause internal damage that isn't visible. A vet check after any heat collapse is the safe choice.
