The 40-year-old from the town of Calatayud in Zaragoza called the police and reported that his two young daughters were trapped in a car, whose locks had been disabled by someone poking sticks into them.
But when police and the fire brigade arrived on the scene, they discovered that the man had not been completely honest with them, Spanish daily ABC reported on Wednesday.
It was not his daughters trapped in his car, but his two cats trapped inside his flat that the man needed help with rescuing.
He asked police to open his front door because his lock was jammed and his two cats were trapped inside.
The man, who has not been named, could now facing a mammoth fine under the region's Civil Protection and Emergencies Law for wasting police time.
The law specifically states that pet owners who call the police to receive faster help or lie to the police are subject to fines of between €150,001 and €600,000.
The man admitted he had exaggerated, but claimed that he had referred to the cats as his daughters because "emotionally he thought of them that way".
