Alexander Pylyshenko, who owns a small zoo in Ukraine, plans to spend an entire year with two lions at his zoo.
Alexander hopes to raise awareness for lions all over the world, and to also raise $45,000 for the construction of a rehab center for lions and other big cats.
Since a year is such a long time - Alexander will split up his time with the lions. Half the time he will stay in their cage, and the rest of the time he will stay in his country house where the lions will join him!!!
This isn't the first time Alexander has done something like this.
Check out a video (above) from the first time Alexander spent an extended period of time with the kings of the jungle.
But that was only for 35 days - a lot less than a year!
Alexander isn't sure when his experiment will begin, but it should happen sometime in 2013.
