Bridavsky selected Rev3 for its connections to Discovery Communications and Animal Planet. Bridavsky had full writing and creative control. The talk show format was made possible by having a subtitled Lil Bub edited with footage of her guests recorded separately. Her first guest was Whoopi Goldberg who met her on The View in April 2013.

Bridavsky sold a variety of merchandise under the LIL BUB moniker and donated much of the profits to animal rescue groups. Some of the money also helped Bridavsky pay off six months of back rent on his recording studio. Bridavsky has a policy to not "approach anybody for anything" and chose to not sign with talent agent Ben Lashes, whose clients have included Grumpy Cat. Lil Bub’s Lil Book: The Extraordinary Life of the Most Amazing Cat on the Planet was released September 3, 2013.
In September 2014, Lil Bub was interviewed by David Yow of The Jesus Lizard for The A.V. Club.
A group of individuals launched a campaign on the website Experiment.com to sequence Lil Bub's genome. The purpose of this project was to better understand Lil Bub's unique appearance (for example, her extra digits). The campaign reached its funding goal on May 25, 2015. The scientists found Lil Bub had a mutation in gene RANK/TNFRSF11A which has also been found in one mouse and fifteen humans. Their research on Lil Bub is published at bioRxiv.
Lil Bub died in her sleep on December 1, 2019. According to her owner, Lil Bub had been fighting an aggressive bone infection at the time of her death.
Lil Bub suffered from osteopetrosis for which she received medication. In late 2012, during the filming of Lil Bub & Friendz, she had a serious health episode and was diagnosed with osteopetrosis by a specialist in Indianapolis. Lil Bub's short legs and osteopetrosis restricted her movement but she was termed "a fantastic waddler." Vibrations from travel also break down the osteoclasts.
