No way. There is a bypass in the cat to prevent plugging.

Test the heat on the exhaust before the cat and after the cat. You do this by aiming an heat sensor at it. And if there isn't much difference then it isn't plugged. If it's on an older vehicle, take it off knock out the insides and put it back on.

Chances are no.
The reason the cat got pluged was people used ledded gas when there car said un leadded only.
Today it is almost impossable to stop one up.

They can. It will kill your power and mileage. A muffler shop can do a quick before and after pressure check to tell you.

It is possible if your engine burns a lot of oil.
