This hilarious video shows how simples it is to make a meerkat LAUGH - by TICKLING its tummy. The meerkat - named Alexander after the Compare The Market Russian critter - was filmed laughing with pleasure at Whitehouse Farm Centre near Morpeth, Northumberland. His keepers regularly stroke his and his fellow meerkat's stomachs - causing them to make a giggle-like sound. Staff member Karen Lovatt said the ticklish creatures are spreading the laughter and sending visitors into stitches.
