Another of their favourite pasttime, i called that ET-ing. You see i used a fishtank divider to separate the little fella from the 2 girls. But there's still a little gap at the side where their tiny hands could somehow pass through a little. So each day they will squeeze themselves there sniffing or trying to reach out to one another. They kinda know each other la.. from the time where the little fella somehow made his way over the other side from the other containe i placed them in before putting them into the fishtank. But sorry guess.. i can't let you all play together! I don't want anymore hamsters! Wahaha...
