The amount of chocolate that is lethal for cats depends entirely on the type of chocolate. The chocolates that include more cocoa such as baking chocolate or dark chocolate are a lot more dangerous than chocolates that are less “pure”.

An exception to this issue can be white chocolate which is not made with roasted cocoa seeds but with cocoa butter which decreases the theobromine levels significantly but it still includes some.
