Dehydration can cause marks to stick around longer than they should. I went to the hospital for dehydration and the nurse pressed on my knee and said, "Oh you are definitely dehydrated."

You might be pale and all that but if it stuck around for over a minute, you might wanna look into that. Could also be poor circulation but my money is on lack of water. Take it from another pale as hell person. Haha.

Cute prints though. My cats do this but it never stays long enough for me to trace them. :( lol. I would love to get a tat of their tootsie prints!!
