I've rescued this kitten off the street today and brought him to the vet to check on his condition, according to the vet, he's pretty healthy except he has a minor injury on his left leg and some worm in his faeces, which we've already gave him the deworm medicine and he's currently on antibiotic as he has some fungal infection. Other than that, he's pretty healthy. Unfortunately, I couldn't keep the kitten because I do have a dog at home and I've tried, the both of them do not get along well.
I hope if there's anyone reading this and is interested in adopting a kitten, please do not hesitate to contact me.

Update (15 June 2015): I've brought the kitten back to the vet for vaccination as his leg injury had fully recovered but he's still on medication for his fungal infection which would have to fed daily for up to another 3 weeks. He's getting more active nowadays.

Update (20 June 2015): the kitten has been adopted by a sincere owner.
