When Scully is doing the cat necroscapy with the barbecue tongs and a sharp knife, in her Marigold gloves and cooking apron, she is interrupted by a phone call. She asks the delivery guy to take over, but despite the fact that she has just been prizing open the dead and buried cat's ribcage, she doesn't give him any protection, and she seems fine to pick up the phone with her rancid cat encrusted gloves, and put it to her face. She's a doctor - the cat's been dead a while, could have had anything in its stomach, William is in an adjoining room. Her hygiene sure leaves a whole lot to be desired! Even live cats can carry diseases.
