Theo watched with vaguely horrified curiosity as Tilcott dove right in to the cat jar. In the blink of an eye he was no longer staring at a man but a cat. A Tom cat. At least he hadn't been set on by a horde of scarab beetles or some such, seeing as things were really starting to have a very Egyptian feel to them. If it really came down to having to touch the remaining jars Theo decided he'd take the dog over the owl. "I have a knife, I could use it to remove one of the other lids without touching it with my bare hands." He wasn't entirely confident that was a viable loophole to becoming an animal but if Umbridge thought it sounded like a good idea he was prepared to do so.
