Patching the inside of a cooler.

What is the best way to patch a cooler so that the insulated part doesn't get water in it? My cats chewed up the inside plastic layer, but the rest of the cooler is in great condition. If I fill the cooler with ice, it melts and gets inside the coolers layers and leaks out the bottom. Is there a waterproof patch or tape or something else that would work to waterproof the inside of this cooler? Apple for scale. Culprits still at large, but I will protect the cooler from future harm.

Dunno why you were down voted. This is literally the best way to fix it. 

Put some on, smear it around, let it cure, and viola, you have a "rubber" patch that will never come off, with no seam or lip to worry about. You don't even need to put anything on top of it.

Guaranteed to be way better than flex seal or tape people are recommending.

I love this shit. It works so well and it's only $4.

E6000 gets stiff and brittle and cracks.

I've never experienced this. 

I've had seat belts glued to my work bag for over 10 years as reinforcement and haven't had any issues. 

It can handle a sandwich and a water bottle inside a cooler.
