At first the tiger cub, who was named Timothy by Grandfather, was brought up entirely on milk given to him in a feeding-bottle by our cook, Mahmoud. But the milk proved too rich for him, and he was put on a diet of raw mutton and cod liver oil, to be followed later by a more tempting diet of pigeons and rabbits.
Here, the highlighted pronouns refer to whom? and also please tell the meaning of `tempting diet'.
Re: tempting diet
him/he- the tiger cub
tempting diet- more attractive food (the writer's view)
