Laura Mellors, 29, from Arnold, Notthingham, started making short films chronicling the daily antics of her pets in 2010 as a hobby.
But the video's popularity sky-rocketed and she now has a global following with 54,000 subscribers to her own YouTube channel.
'I was just bored one day so I made a film about my guinea pigs, Gus and Hercules.
'I'd bought a new cage which gives them different compartments and levels to climb on and I was intrigued to see how they would react to it.
'I uploaded the video to YouTube and within a few days I was getting really positive feedback and requests for more videos.
'Someone asked me to make a video showing them how to construct the cage so I did and it just snowballed.
'My guinea pigs are now followed and sent fan mail. People ask what they're up to.
'When I was at the London Pet show last year a little girl and her mum even came up and asked for my autograph.
'The strangest thing happened last October. I'd told people on Facebook I was going to America on honeymoon and I got requests to meet them so I ended up meeting two families while I was there.'
Laura and her husband James, 30, a project engineer, now share their home with seven guinea pigs, Billy, Bobby, Fozzy Bear, Brian, Bo, Alfie and Gizmo.
She earns around £2,000-a-month from her YouTube videos as well as selling guinea pig goods through her online shop.
Laura added: 'At the moment I work two or three days a week making videos and updating the guinea pigs' updates on Twitter and Facebook.
'If I don't post regular updates I get messages from people asking if the guinea pigs are okay.
'People seem to love the videos. It's a joy to do something for a living which is also a passion.'
