Adjectives ending in -s or -x only change their feminine forms when plural

Look at these masculine cases:

un homme heureux et des hommes heureux
a happy man and happy men

un vent frais et des vents frais
a cool wind and cool winds

le gros chat et les gros chats
the big cat and the big cats

Adjectives ending in-s and -x stay the same in masculine plural forms.

BUT

Look at these feminine cases:

une femme heureuse et des femmes heureuses
a happy woman and happy women

une brise fraîche et des brises fraîches
a fresh breeze and fresh breezes

la grosse souris mais les grosses souris
the big mouse but the big mice

Note that the feminine plural forms of these adjectives are regular (add -s on the feminine singular form)

Title

It seems that the title of this lesson is incorrect, I believe it should read: "Adjectives ending in -s or -x change in the plural forms only when feminine" : )
