Little did he know Kheng the croc would grow to be a over metre long!
Looking after the reptile is a full time job. Wattana has to wash him, brush his teeth before bedtime and the huge task of feeding the croc.
"Wild animals are easy to find but friendly wild animals are difficult to find. I have raised him to be friendly," he said.
Kheng is not like other crocs though, instead of hanging out at the local swamp, this gentle giant prefers a night in watching TV with his owners.
Well, they do say staying is the new going out!
