Wuthering Heights indeed

Yesterday, my 7 months old kitten, Heathcliff, fell off the kitchen window sill, which is on the second floor.
He must have hit hard on the concrete and perhaps even on the steps leading to the building entrance. I found him disheveled and bleeding.
He's spent the night at the vet. I'm very scared and anxious as to what the damages are.
Here's to Heathcliff, my poor little cat :-(

(these two cats are Somali, the same breed as my kitten)

Here are things he likes:
He loves Pumpkin seeds
and yoghurt, all things fruity and sweet
but especially my morning cereal!
