Don't think it'll do much damage but if the cells are breaking up it's going to be worse on emissions

Some people have broken up the bits inside a CAT to make a make shift De-cat zorst system.

The CAT is purely there for emissions, if it doesn't perform it will not pass an MOT emissions test and there for fail.

A new one is best. And by the way your front CAT is your only CAT on a car, the small box near the back box is a silencer

if left as it is, it will find its way to the end of the pipe, and block it...leading to loss of power (like a top speed of 30/40mph!) its becuse the elements inside turn around to the side and get sucked/blown into the back of the cat, completely blocking the pipe.
