Not if you only give the engine a couple of turns. The amount of unburnt fuel getting through to the cat will be minimal if any as the car has been stood for a few months and would not do any damage. It is better that you get the oil to the top of the engine, having hydralic lifters more damage would or could be done by the engine turning with no compression and lack of oil.
