How would i get cat urine smell out of my leather couch??

my cat pee'd on my leather couch in the middle of one cushion then right between two of the cushions... fully on the leather, in the crease and they are sewn in.. i was thinkin baking soda may soak up some then some leather cleaner? i just dont want to spread it around or saturate it any more. and i dont want to damage the leather. its carmel colored, not shiny but not suede..
