For ps4 to throw honey put it in your last spot in your hot bar and press L1 L2 and control pad right arrow and you throw it right when it goes into its hole however if it burrows down without you throwing any honey the tameing will go down
On the normal tame rate I tamed a level 45 rat, it took 19 honey. Take about 5 extra honey until they get the correct amount needed. You have to throw the honey the second it burrows or you'll miss your opportunity and lose taming effectiveness and the taming percentage will go down.
It may not make a difference...but to whom it may concern; you dont have to put the honey in your last slot...it can be in any slot. This might help those, who like me, have a broken right d-pad (xbox).
