Quite right! Any two year old male should weigh no less than 4 kg, so this boy had lost almost 50% of his weight, and possibly more. Sadly, once they lose this much weight it's very rare that they recover.
Shame on them.

Thats what my husband mentioned to me, that I should still try, but not to get to attached until he would at least support his own weight.
I think one should always try, but should do so knowing the odds are against them. Even if you had been able to get him to a vet, I doubt he would have survived the car trip and exam.
