We've had these two for a year now. The one on the left has earned the name Baby, because him baby. The one on the right is Menace, because he likes to cause problems, like destroying the blinds and waking Mom up at 3 AM with what she describes as "dexterity olympics" (or, you know, knocking her meds off her dressing table)
Oh, yeah, I left out the thing about me needing new doorknobs for my bedroom because Menace figured out how to open the lever-style knobs we had! Seriously, he's trouble
