The record-breaker is among the latest stars of the book, which has been marking the extremes of achievement since 1955.
Ludo the Maine Coon is a supersized cat measuring a whopping 118.33cm (3ft 10.59in) in length from his nose to the tip of the bone in his tail.
Ludo was no bigger than the other kittens in his litter when he was taken home to Wakefield, by his owner Kelsey Gill in 2014.
She describes him as a “relaxed and laid back” cat who loves a good sleep.
Caspa, a nine-year-old llama who lives on a farm in Porthmadog, North Wales, also takes his place in the book because he can clear a bar standing at 1.13 metres (3ft 8.5in) high.
Sue Williams, who has owned Caspa since he was two years old, describes him as a “total diva” and the envy of all the other llamas on the farm.
Austrian stunt man Josef Toedtling, 36, made it into the record book for a full body burn - or being set alight - with no oxygen, which lasted five minutes 41 seconds. He beat the previous record by 16 seconds.
Mr Toedtling, who has 49 movie credits, including the 2015 remake of Point Break, also holds the record for furthest distance pulled by a vehicle during a full body burn, reaching a huge 582 metres.
Being set alight is among the skills he has learned on film sets over his career. He applies a flame retardant gel to his face but everything else is on fire, GWR said.
Florida pensioners Charlotte Guttenberg and Chuck Helmke are named the most tattooed senior citizens - male and female - in the world.
Ms Guttenberg, 67, has covered 91.5% of her body with tattoos since first being inked just 10 years ago.
Mr Helmke, 76, who sat beside her in the tattoo parlour to help to ease her nerves as she had her first tattoo, has 93.5% of his body covered in tattoos. All of this work was done in the last 16 years apart from one army tattoo.
Standing 96.41cm (37.96in) tall from the floor to her haunches, Lizzy the Great Dane is named the tallest living female dog.
The Florida-based dog is so tall that her food bowl has to be put on a chair because she cannot reach the floor to eat, the GWR said.
