How does changing the first line of the logic equation make any difference?


Because a logical statement has to have valid inferences.  Your statement that all cats see in the dark was invalid since some cats do not see in the dark.

Read the statement again.  I didn't say "all cats can see in the dark", I said "cats can see in the dark".   Both premises were factual.   Midnight is biologically a cat and cats are scientifically proven to have the ability to see in the dark.  The logical conclusion is that Midnight should be able to see in the dark.   But Midnight is actually blind.   That's a logical curveball.

Your statement is not valid, just as someone else familar with logic said the same thing.

Your statement implied that all cats can see in the dark, which is not true.  You could also have said that most cats see in the dark, which is a true statement but you couldnt draw your conclusion from that premise.
