Meet the AcroCats — 27 former malnourished street cats who have become pampered performers at Britain's biggest circus.
The Borissov family, who have been circus performers all their lives, began rescuing cats from the streets of Angers in South West France as pets.
The family are big animal lovers and have rescued many creatures from miserable lives.
Once the family had adopted six cats from the streets, Roseline wondered if they could be trained to join their circus act.
"They are difficult to train. Cats are very independent and when they don't want to work they don't work," Roseline said.
The family now have 27 cats who are all trained, or in training, to perform in the show.
The cat troupe leader is seven-year-old Felix who performs a "Supercat" high leap from a pedestal into his trainers arms below.
The youngest performer is Junior, who was found abandoned in a French shopping centre, and now dazzles crowds with his tightrope walking.
"These are just regular cats and they don't do anything that cats don't naturally do," Burton told BuzzFeed News.
"These are pet cats who will do tricks for treats. They are fed fancy sausages from France and the finest paté."
"These cats are cats that would be still living on the streets or dead if they weren't in the circus," he said.
"Animal welfare is very important to me. We wrote the first ever code of conduct for animal welfare in circuses."
The Borissov family also have rescued horses who feature in their show.
These two were rescued from a slaughterhouse moments before they were due to be killed.
But it is the cats who have become the stars of the show this year for the circus' 30th anniversary.
"It is no longer the old days of circuses, people do not want to watch a man poke a lion with a chair until it roars like they did in the 1900s," Burton said.
"The reason this is such a good act is because it's just a lady who loves her cats playing with them."
