Meerkat pup Tunnock is small enough to fit in a teacup and weighs just 96g, the same as four of his namesake teacakes.
He is one of four new additions, along with a set of triplets to the meerkat enclosure at Blair Drummond Safari Park near Stirling, Scotland.
Tunnock, just three weeks old, is being fed a milk formula.
All four of the pups weighed just 30g at birth and will soon learn to dig and forage in the sand for grubs. Other new arrivals are a baby antelope and white rhino.
