Rexie is a 3-year-old male cat who's very expressive when it comes to showing emotions. My personal favorite ones are those where he shows off his little tongue. Of course, it's not like he sticks his tongue out and waits for me to take a picture. I'd say it's more of a teamwork kind of thing - between a photographer and a model (in our case, a meowdel).
It's important to catch the right moment on camera for the first, and do all the tongue movements possible for the latter. But the outcomes are never disappointing!
And yes, Rexie is handicapped but it by no means stops him from being awesome!
