Most of us will know what it feels like to pack on a few extra pounds over winter, so spare a thought for these Siberian tigers who were pictured looking a little chubby at a zoo in China.
The endangered animals were spotted prowling their enclosure at Shenyang Siberian Tiger Park in the country's northeast in temperatures of -30C.
Shenyang is a second Chinese zoo to be exposed for housing overweight animals after several fat cats were pictured at Harbin zoo last month.

The animals appeared to have packed on the pounds over winter as temperatures plunged as low as -30C
These animals were pictured in Shenyen after more overweight tigers were spotted in Harbin last year. At the time keepers said the animals naturally gained weight in winter, and would lose it again in summer
Despite keepers insisting that the chubby animals were in fine health, their appearance caused concern among experts
At the time many criticised the zoo for overfeeding the tigers, though keepers told the People's Daily that the animals naturally gained weight in winter to protect from the cold, and would lose the weight in summer.
International experts disagreed, however, saying the animals were seriously ill and needed to be given a better diet and more exercise.
In an effort to slim the animals down, they were later filmed running around after a drone.
Shenyang has a chequered past when it comes to caring for their tigers, and in 2010 was heavily criticised after 11 animals starved to death or were shot.
The biggest of the big cats, the Siberian tiger once roamed throughout Korea, northeast China, the Russian Far East and eastern Mongolia. But the wild population today has been drastically reduced.

Siberian tigers once roamed vast swathes of territory across eastern China and Korea, but are now endangered
Siberian tigers are naturally the largest of the world's big cats, though these animals appear to be larger than most
Laws have been put in place to protect the tigers and many zoos engage in breeding programmes, with the population now listed as stable, though few remain in the wild
