My Story is a regular feature on guinnessworldrecords.com, where record holders reveal their experiences.
Today's guest blogger is 14-year-old Chloe Macari from Rosyth, Fife in Scotland (pictured right, with her sister Nicole, 15).
Chloe's pet Truffles has achieved worldwide fame after setting a world record for the longest jump by a guinea pig with an incredible leap of 48cm.
Here, Chloe tells us what it's like to own a record-breaking animal.
Truffles first came into my life during a visit to a local pet shop four years ago.
Up until that moment I had always wanted a dog, but I wasn't allowed to have one.
My older sister Nicole picked out Nibbles, a white and brown guinea pig, while I opted for his black and white brother.
In the past I had often felt jealous of friends who owned dogs, but that all changed once I took my new furry friend home.
Truffles began his journey into the history books a couple of years later. It all started while I was browsing through the 2011 edition of the Guinness World Records book at my local library.
Flicking through the pages I noticed entries for the fastest run and longest jump by guinea Pigs which had been set during a publicity event in London for the launch of the animated movie G Force.
Inspired, I went home and immediately told my mum that I thought Truffles could break the records if I trained him.
After getting mum's blessing, I set about preparing an area of our house as an exercise area for our guinea pigs.
I created two jumping positions from a pair of shoe boxes which I weighed down by filling them with books, then covered them with old cushion covers to make them soft for landing.
Me and Nicole always spend at least an hour every day taking care of Truffles and Nibbles, from cleaning their cage, to giving them a brush as well as spending time encouraging them to exercise.
It was during this time that I would try to get the pair of them to attempt jumping a gap between the boxes.
Cucumber is their favourite food, so I placed the guinea pigs on one box and the cucumber on the other and then gradually moved the boxes further and further away from each other.
It soon became clear Nibbles did not take to jumping, instead deciding to hop down and run around before cheekily stealing the cucumber from the opposite box.
Truffles, on the other hand, appeared to really enjoy the challenge.
Within an impressively short time, Truffles was able to beat the previous record of 20.5cm set by a guinea pig called Diesel in London in 2009.
Over the Christmas holidays I showed my family that Truffles could beat the record, leading my granddad John to encourage me to get in touch with Guinness World Records.
Soon after making an application for Truffles through the Guinness World Records website, I was sent a list of guidelines for the longest jump by a guinea pig record category.
In order for an attempt by Truffles to be valid, it needed to take place in a public setting. I would also need to record video of the jump with a tape measure present, and would also need to have creditable witnesses to sign to say Truffles did it.
I decided to organise Truffles' world record attempt at my local scout hall (I'm currently a patrol leader in the 41st Fife troop), and called on scout leaders there to help verify the jump.
On the day of the attempt, a group of people gathered at the hall to see if Truffles could make animal history, including a number of my friends from scouts.
On cue, Truffles managed to jump a record-setting 30cm, causing the hall to erupt with cheers.
Everyone was so excited to see a world record being broken and I was so proud of him.
My grandad John was there too and he took him around the hall to meet all the scouts on a lap of honour.
A few weeks after sending the evidence off, a Guinness World Records certificate arrived in the post - it was such a great feeling.
It didn't take long for news of Truffles' feat to spread around the small village where we live -everyone was talking about his world record.
We were soon interviewed by local newspapers, and also featured on an ITV documentary called Super Tiny Animals.
All this attention on Truffles was really exciting, but it also meant more people became aware of the world record and could inspire other guinea pig owners to get their pets to challenge his jump.
If another guinea pig beat the jump, Truffles would not be selected for the Guinness World Records 2013 book.
With this in mind, me and Truffles set about improving his record.
After another period of training during the Easter holidays, tempted by curly kale, Truffles managed to jump an incredible 48cm.
Shortly after sending through the evidence of the new attempt we received confirmation that the jump had not only been accepted as a world record leap, but that Truffles would indeed be appearing in the next edition of the Guinness World Records book - he had done it!
Despite already having had quite a bit of coverage last time around, with Truffles now making it into the book we found ourselves once again in the news. Popular websites like Buzz60 were now covering the story meaning Truffles was now all over the internet as well.
My mum tells everyone now that Truffles has retired, but if anyone does break his record, I'm sure he could do it again.
He is still fit and healthy and we love him to bits.
It feels amazing to be the owner of a Guinness World Record holder, helping him train has been one of the best things I have ever done.
Everyone is so interested in him, I can't count how many times I have been asked about the whole story - I like that everyone loves my wee guinea pig!
