Joke is kind of spoiled in English, as the "take help from a cat" phrase is not necessarily Ran actively wishing for Chen to help out, but rather just using a common saying for "ahh I'm so busy".
Chen's line in panel 4 would make a lot less sense that way though, so I left Ran's line in panel 2 as is.
Chen!!!Please use mine, Ran-sama!!*pop out*Ah~ Busy busy!!SalonpasCompress*rushing about*I'm so busy I'd even take help from a cat's paws...Phew!Nyaaーn
