So what you're really saying here is that it might be possible that the glass was installed by a minority bidder. And, probably not being sanctioned to the usual safety checks offs (again, preference based), the glass could break on a 'cat pounce' and little Marshall is toast.
I guess next we'll be told that little Marshall's parents will get a bill for the broken glass. :)
Anything is possible. I am sure that the over-expensive plexiglas or whatever it is is sturdy enough, if it was bolted/glued down properly. Hopefully the installers weren’t all affirmative action hires too.
