Because the insulation breaks down and leaks HT current, leading to weak
spark.

Weak spark causes excess HCs to reach the cat, overheating it to the point
of "sintering". Sintering is where the cotton candy-like surface of the
cat's element begins melting and blobbing, greatly reducing its effective
surface area, capacity and life.
