No, it is not a good idea to kill all the cats in the black death in order to deal with a rat problem. Cats are natural predators of rats and play a crucial role in controlling the rat population. By removing the cats, the rat population would likely increase, leading to an even bigger rat problem. Additionally, cats are domestic animals that provide companionship and mental health benefits to their owners, so killing them unnecessarily would be cruel and unjust. It is important to find other methods of rat control that do not involve harming or killing innocent animals.
