A 2-year-old Florida panther is released into the wild by the Florida Fish and Wildlife Conservation Commission (FWC) on April 3, 2013 in West Palm Beach, Florida. The panther and its sister had been raised at the White Oak Conservation Center since they were 5 months old. The FWC rescued the two panthers as kittens in September 2011 in northern Collier County after their mother was found dead. The panther is healthy and has grown to a size that should prepare him for life in the wild. (Photo by Joe Raedle)

Meet Booboo, the 2-year-old guinea pig. Her hobbies included eating chicory and posing for pictures. Described optimistically as ‘spirited’ by owner Megan, she can generally be found knocking about with her guinea pig crew, Titi and Teddy. But don’t worry, these gangsta guineas are lovers not fighters (didn’t the chicory give you a clue?). In fact, they’re pretty cerebral, often to be found quietly reading a book, or staring contemplatively into the distance next to a sprig of lavender, that kind of thing.

A UFO enthusiast who found himself locked in the iconic Roswell museum has shared the pictures he took with aliens to pass the time. Chris Burton, from the U.K., had dreamed of visiting Roswell, N.M., since he was a child but was stunned when he found himself locked in the International UFO Museum and Research Center during a recent trip. The 42-year-old used the unique opportunity to get interactive with the usually out of bounds exhibits and set up some funny snaps with the extraterrestrials – posing for a beer with one alien and taking a nap with another.

Three-year-old tawny owl, found abandoned by its owner, is agoraphobic. Multi-skilled Bertie also likes to help Mr Middleton make a cup of tea – and is fond of sitting on top of the kettle. Mr Middleton said the domesticated owl, which he adopted after it was left abandoned on the ground, hates the outdoors. The domestic owl casts a watchful eye over Mr Middleton's handy work. The creature was found by the organic farmer abandoned on the ground.
