No, I never had a clogged catalytic converter. That shouldn't normally happen, unless you burn contaminated fuel leading to an incomplete combustion, oil or coolant leaks into the exhaust, engine running rich or something else not right with the combustion in your engine. You mechanic is right, the primary cats are way up in the engine bay and hard to get to. Should find the root cause for the clogged catalytic converter and not just clean it.

thank you yes it might be oil leak due to cam adjuster failure for a while last week i had to change all four of them and the stored codes removed so after that I got an cat code so i went to check it and it turns that its clogged i finally managed to open them from the hod and cleaned them
