"Don't leave your pets locked up in a hot car."
It sounds quite simple, but it's something that still happens too many times.
But for anyone still left wondering why leaving a pet in a car alone for any period of time is a bad idea,T'mielle White from Orange RSPCA in NSW's Central Tablelands has the answer.
"Pets have a harder time cooling themselves down than we do," she said.
"There's no access to water, no fresh air and obviously cars get very, very hot and they can't escape it.
"If you see something like this, you can either call the police or the RSPCA cruelty line and the inspectors can be called to the scene."
Asked if it is ever a good idea to leave a pet in a car, she gave a firm "no."
"Treat them as if they were a baby and you would never leave a baby in a car," Ms White said.
"They're a life and it gets hot in a car so never leave a pet in there.
"Even leaving the windows down doesn't attract much air. If you've got an animal or a baby in the car with no windows down it's going to be a disaster."
