Why is my display flickering?

I have a 2013 late MBP with a Retina display, and the youngest of my indoor cats decided to see it my computer was edible and began to gnaw on the upper left portion of the screen when I was sleeping the other night, and I woke and noticed the below marks on the screen. That said, the screen now has intermittent screen flickering issues.

Is there a way I can fix this issue without having to replace the LCD / display assembly. I am not opposed to disassembling the display assembly if there a permanent fix for the display.
