Change logo that's about tailless mammal (7)
I believe the answer is:
rebadge
'change logo' is the definition.
I know nothing about this answer so I can't tell whether this works.
'about tailless mammal' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'tailless mammal' becomes 'badge' (I can't justify this - if you can you should give a lot more credence to this answer).
're'+'badge'='REBADGE'
'that's' is the link.
Can you help me to learn more?
(Another definition for rebadge that I've seen is " Launch with new logo".)
