I don't know if this is an older or newer design by The Mountain, but it definitely runs a wee bit smaller than the other Mountain shirts I own in the same size. Maybe it was just the one I got, but I was surprised as Mountain shirts generally seem to run a little large. Just be warned.

Other than that, as usual with their items, the graphic is vibrant and of great quality. And ridiculous, but you had to know that. I purchased this one as my other Mountain kitten shirt had only 7 cats, which seemed like a waste of precious kitten real estate. So maybe I answered my own question: this is a newer design and they are supersizing kitten levels, but at a detriment to shirt fabric?
