Animals Small and Great
Q The puzzle expert Will Shortz says that a mathematician named Douglas Hofstadter came up with the following word puzzle:

Think of a four-letter common noun that names a tiny animal. Now change the second letter of the noun to the next letter in the alphabet. What larger animal, also four letters long, do you come up with?

HINT:Don't look at this hint if you don't need it.
The name of each animal begins with the letter g.

A The first four-letter animal is gnat, and the next is goat.
