See feline is circling old and new sites (9)

I believe the answer is:

locations

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

'new sites' is the definition.
'locations' can be an answer for 'sites' (I've seen this before). I am not sure about the 'new' bit.

'see feline is circling old and' is the wordplay.
'see' becomes 'lo' (archaic exclamation meaning 'look!').
'feline' becomes 'cat' (cat is a kind of feline).
'circling' means one lot of letters goes inside another (circling can mean going around or containing).
'old' becomes 'o' (abbreviation).
'and' becomes 'n' (common abbreviation for 'and').
'o'+'n'='on'
'is' enclosing 'on' is 'ions'.
'lo'+'cat'+'ions'='LOCATIONS'

Can you help me to learn more?

(Another definition for locations that I've seen is " Places, sites".)

I've seen this clue in The Telegraph.
