An ursine scratcher in Carry on Cleo is fairly awful from the start to begin with (4,4)

'an ursine' is the definition.
I can't tell whether this definition defines the answer.

'scratcher in carry on cleo is fairly awful from the start to begin with' is the wordplay.
I cannot quite see how this works, but
'scratcher' could be 'claw' (I've seen this in another clue) and 'claw' is present in the answer.
'carry' could be 'bear' (bear can mean to transport or carry) and 'bear' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
