We love our dogs and cats so much that we have learned how to pet them…in some way, sometimes they are so unpredictable and moody, especially cats, but if you think they are not easy to please, then do you know how to pet a piglet or hedgehog? Blogger Adam Ellis has created a comprehensive list of charts that will show you where you can and cannot pet your animal friends. And I must say, some of them are kind of shocking, like… there are people who knows how to pet a unicorn! How amazing is that? Sure I will keep that in mind in case I meet one someday. Also, there is The Wolverine… ugh, but that’s another story.
