Catalytic poisoning
Catalyser poisoning requires irreversible binding with chemicals from the fuel, such as lead or to a lesser degree sulphur. With decent modern fuels, this is unlikely to be a problem. Coating of the catalyst with fuel and lube oil will decrease efficiency but is reversible once the catalyser gets up to operating temperature for a reasonable period

As long as any car is taken for a decent run between periods of short tripping there should be no problem with the CAT or DPF.

Indeed, especially when combined with auto stop/start.
