Crossword Genius

Getting back, have left bed for cat (4)

Ross

I believe the answer is:

puma

'for cat' is the definition.
(puma is a kind of cat)

I can't explain the rest of the clue.

(Other definitions for puma that I've seen before include "Big cat" , "Cougar" , "American wildcat" , "International rugby player" , "South American carnivore" .)

I've seen this clue in The Times.
