Kirk has 25 marbles and 14 seashells. What information is needed to find the number of marbles that are NOT cat's eyes?

To find the number of marbles that are NOT cat's eyes, we need two pieces of information:

1. The total number of marbles Kirk has.
2. The number of marbles that are cat's eyes.

In this case, we are given that Kirk has 25 marbles. However, we don't have the specific information about how many of those marbles are cat's eyes. Without knowing this, we cannot determine the number of marbles that are NOT cat's eyes.
