There are few things more heartbreaking in life than losing someone close to you, especially if it’s a beloved pet. When I lost my childhood pet at the age of 13, I was so distraught that I had to take the day off school, and even though I’m almost 25, I still have a picture of him pinned to my wall.

The loss of a pet is difficult to deal with because animals are impossible to replace. However, if you’ve got a large amount of disposable income, it doesn’t need to be permanent, something which Barbra Streisand decided to take advantage of when she cloned her dog – twice.

Described on Instagram as her “beloved girl”, Streisand tragically lost her dog Samantha in May of last year. Instead of mourning the loss before buying another dog, she decided to go one step further and have cells from Samantha’s mouth and stomach taken to clone her.

While cloning a pet might sound extreme, it’s actually been around for more than a decade, with the first known commercial pet clone taking place in 2004 to the tune of $50,000. By 2015, more than 700 dogs had been cloned for their bereaved and wealthy owners.

“We cherish every moment of the 14 years we had with her,” Streisand wrote of Samantha last year.

Cloning a pet is obviously done in an attempt to keep beloved qualities of a deceased animal alive, however, it’s been proven that these similarities will not be exact, and the cloned animal will be, on average, about as similar as an identical twin.
