Looking for 2 specific cat videos

During my random travels around the internet, I saw two short clips that I'd like to find, and if possible, the full versions of said clips. One is a video of cats lunging towards people who were edited in to look about mouse-size; I think the people might have been dressed in tactical gear. The other was of a door opening, showing four or five cats standing in the doorway on their back legs, like people.
Does anyone have any idea what I'm talking about?

looking for cat videos on the internet?
Kinda like looking for a very specific hay in a haystack.
That's also 100 feet tall.

Hope you find them.
