Acrylic crazing

[creepervision]

I have had this tank up for 6 months. I got the tank used. I was told a cat did its business in the corner. Just wanted to see what you guys think about the crazing. I ran it thought google and was told to drain the tank. That would be an undertaking. What do you think, is it safe? the tank is 8*4*30.
