Hi

Would suggest that first and foremost you ensure the kitten is warm - have you got a heat pad (covered) that you could place him on? You could try some nutridrops - sometimes this helps give them a little energy. All the suggestions re feeding are good but I fear you may lose the battle here but I sincerely do wish you the best of luck with him.
