Drunk Possible problems with cat

Hi everyone, has anybody ever had a problem with their cat restricting flow when the engine is warm/hot even if the insides of the cat has not broken up.
I'm at the end of my patience with my car and losing the will to own it very quickly.

I've not heard of this problem before, what makes you think the cat is at fault in the first place?

How do you know they haven't broken up?

When the cat failed on our old Mondeo, we had no warning, the honeycomb just sort of folded in on itself but that affected us under load whether the car was hot or cold.

I'm not sure how far down the diagnostic path you are but ss the MAF OK? That would be my first suspectclosely followed by looking for fuel starvation/blockages
