After 10 years, three apartments, and two spirits that have passed through in their presence, Nyxi, my 2 year old Toyger , smashed one of the ruby, patterned glasses (Moroccan). I actually felt she was going to do this one day, she is just so active when she jumps up to her 'alter'. I am now just left with one, to which I will replace them both, obviously keep the remainder glass.
