This a groundbreaking scientific breakthrough! After 20 years of trying to increase the cheetah population, there might be hope for their species yet! 

Columbus Zoo, Ohio, has reported that two cheetah cubs (a male and female) were born February 19th, 2020. The birth is thanks to a procedure that took place at the Smithsonian Conservation Biology Institute. For the first time in history, US scientists were able to delivery two cubs via vitro fertilisation (IVF), using a surrogate cheetah.

The surrogate mother, Izzy, is a three-year-old cheetah who carried the eggs harvested from six-year-old Kabibi, and sperm from a cheetah at the Fossil Rim Wildlife Center in Texas. 

Timeline of the historical procedure according to the Smithsonian's National Zoo website:

• Nov. 14 and 18: The female cheetahs were given hormone injections to develop mature follicles.
• Nov. 19: Eggs (oocytes) were taken from Izzy and Kibibi. Neither had reproduced previously.
• Nov. 19: Semen from male cheetah thawed and eggs fertilized.
• Nov. 21: Team implanted nine embryos in Isabelle (Izzy) and six in second cheetah, Ophelia. A typical cheetah gestation is 93 days.
• Dec. 23: Izzy was confirmed pregnant via ultrasound, which appeared to show two cubs. The ultrasound confirmed that Ophelia was not pregnant.
• Feb. 16: Izzy's care providers begin an around-the-clock video birth watch
• Feb. 19: Cubs born

How amazing is that? Thanks to all the hard working scientists who are keeping these beautiful creature from going extinct!

Researchers in Alberta, Canada discovered new species of tyrannosaur - a 79-million-year-old tyrannosaur named Thanatotheristes degrootorum — which means "reaper of death". The fearsome predator lived 79 million years ago during the Late Cretaceous period.

Ever wonder how cats became domesticated? Or why on Earth humans decided to bring in the adorable and small predators into our homes in the first place? You've come to the right place! 

Tumblr user, Koryos, who studies animal behavior, has written this extremely informative post about how the once-mighty predatory now sits indoors pampered. 

It's actually quite fascinating and Koryos has done a wonderful job of explaining it so well!

You are probably not surprised to hear that dogs have been helping people with disabilities for centuries. Twitter page @DisabilityHistory takes a look back at art and photos that reveal all the good things done by these good boys many years ago. It has been suggested that the earliest surviving illustration of a guide dog from Western Europe dates to the late fifteenth century.  But there are actually several earlier depictions of guide dogs that survive in medieval manuscripts.      

This is amazing! Delaware is making history as the first and only no-kill animal shelter state in the country! According to Best Friends Animal Society, a non-profit animal welfare organization. for a state to be recognized as "no-kill," it must achieve a 90% save rate for all the animals that enter -- and Delaware did that. 

Brandywine Valley SPCA, which has three locations in Delaware and cares for more than 14,000 animals each year, have multiple programs implemented on how they achieved this no-kill status!

You've probably never heard of him, but you've almost definitely seen his photographs. I'm talking about Walter Chandoha, the American photographer, cat dad and husband, who photographed cats for most of his life and was the virtually the pioneer of cat photography. Here is his story. 

What an accomplishment! Thanks to these adorable furry companions, Thomas Panek was able to partake and complete the New York Half Marathon, making him the first blind person to ever do so! See the images from the marathon below:

The relationship between humans and animals has been evolving for thousands of years, and animal companions are just as loved today as they were in the ancient world. It wasn't always just cats and dogs, however. Pets in ancient history consisted of creatures from all branches of the tree of life. Reptiles, birds, fish, and many other creatures have lived with us since time immemorial. These historical pets are as fascinating as ever, and they give us a glimpse into the everyday lives of our ancient ancestors. Via: Ranker
