A pair of endangered tiger cubs have been exploring their enclosure as they grow in confidence.<br /><br />Their mother Mishka, aged seven, gave birth to three Amur tiger cubs at Banham Zoo in Norfolk on 1 May.<br /><br />One of the triplets was found dead six days later, with a post-mortem examination recording that it had “struggled to suckle from Mishka”.<br /><br />A spokesman said that the first eight weeks are “incredibly risky” for tiger cubs.<br /><br />The two surviving cubs are “doing well and growing in strength” and “growing in confidence as they begin to move around more”, Banham Zoo said.
