Sandra D. Yoshi-chan. xD Okay, her collar only says Sandra.

My mom met her for the first time the other day and called her a money cat. Money cats, Lucky cats, and the like, seem to be symbols of welcome/luck/protection. (As Sandra nose beeps me in confirmation.) Because of all this fun cultural stuff, (mostly Wiki-Surfing really ^_^;) I learn that "Yoshi" is the word for "luck," and I remember that suffix -chan is for cutesy things.

Sandra D is because when I adopted her, her name was Sandy. All I could think of was Grease.
