One good cutting hair for catty females (9)

Ross

I believe the answer is:

tigresses

I'm a little stuck... Click here to teach me more about this clue!

'catty females' is the definition.
The definition and answer can be both animals as well as being plural nouns.
Maybe they are linked in a way I don't understand?

'one good cutting hair' is the wordplay.
'one' becomes 'i' (Roman numeral).
'good' becomes 'g' (abbreviation).
'cutting' means one lot of letters goes inside another (some letters cut their way into a word).
'hair' becomes 'tresses' (tresses are locks of hair).
'i'+'g'='ig'
'ig' inserted inside 'tresses' is 'TIGRESSES'.

'for' acts as a link.

Can you help me to learn more?

(Another definition for tigresses that I've seen is " are ferocious".)
