strange vegetation

Shu and I were worried sick about Kecik the whole of last night.He didn't come home and as much as I know how he never answer my calls,I went around outside looking for him last night.Finally,Shu told me to just come inside.We prayed for him to come home.He did.This morning.Shu said he looked like he got into a fight.I have no idea where he went but I'm just glad that he's home.We have to take him over to the vet and check on those strange markings on the back of his neck :/ Hello,Dr. Clement!
