You don't need to be a biology wizard to know that two different species of animals cannot originate from the same mother. Or so we've been led to believe anyway. But take a look at these pictures and prepare to have everything you've ever known turned upside down!

Well ok, not quite. But these animal sisters and brothers from other mothers look so bizarrely similar that you could be forgiven for thinking that they share the same parents. Take a look at this list compiled by Bored Panda to see what we mean. Don't forget to vote for your favorite, and feel free to send us your pictures if you have any pets that look suspiciously like siblings!
