They say that animals are difficult to read but honestly, this has not been my experience, at least with Mikey anyway, he is a pretty easy read.
As you can see here, Mikey makes it pretty obvious how he is feeling. LOL
I was in the hall taking pictures instead of playing like Mikey wanted to do so he jumped up on his rail and through himself down with a big sigh...LOL
Model is Mikey... Bored.
