On day 255 of living in the Arizonian wilderness, the TikTok creator, who goes by the name "That Guy," heard a noise under his trailer and found a little speckled gray kitten.

"What are you doing in the desert, my guy? Actually, I checked; you're a girl," he exclaims in a now-viral clip.

He wonders how the coyotes didn't get the kitten and where it came from before exclaiming: "I really don't like cats, but I guess you're my expense now."
