Do not feed the animal. Cool the animal down to gradually reduce their body temperature back to normal as much as possible. If there is no injury, avoid transporting the animal to a vet as this can increase their stress further. This should be the last resort.
If an animal is convulsing or unconscious it needs to be taken to a vet as soon as possible.
When picking an animal up, always wear gloves or place material over your hands for protection. Pick the animal up from underneath and place it on an old towel or box dampened with water. Be careful to avoid the animal’s claws, mouth or beak as it may feel threatened and could attempt to defend itself.
Take the animal inside where it is normally 10-12 degrees cooler than the outside. The aim is to remove the animal from the heat for at least a few hours to allow their body temperature to reduce. Keep the animal in a cool dimly lit area.
A shallow container (ie. lid of a jar) can be used to place water in and it is preferred the animal laps at the water themselves. If it is too weak to reach the water, use an eye dropper to give small amounts of water in the mouth.
