We cat lovers joke about our slumbering pets, assuming they would probably sleep through a fire or would exit the burning house with no thought for us. We tend to assume that the only threat to a burglar would be that he might trip over the cat in the dark. Dogs, so people assume, are the “hero pets,” warning their owners of fire or other dangers.
But in fact there are true stories of cats waking up their owners when the house was on fire or raising a ruckus when someone was breaking into the house. There are even cases of cats saving the lives of people (or other cats) who were being attacked by vicious dogs. Yes, cats do seem to be selfish creatures, but they do have their noble moments.
