Elisabeth turned her head instinctively when she heard clicking noises behind her, there was a man, who apparently thought she was an actual cat, she tried to say something, but it came out more like a 'Mrowp' instead. She wasn't sure if this man was a muggle or not, so she couldn't just transform out of her animagus form right away, though she was afraid of getting stuck.
For now, Elisabeth resolved to play along, at least until she could tell whether or not the man was a muggle, perhaps if he was a wizard she could catch a glimpse of his wand, or something similar. She slowly padded over towards the man, going towards his hand, as an actual cat would, most likely to be petted, she wasn't very fond of being petted, but she was a cat right now, wasn't she?
Elisabeth decided to try out a theory, she'd play along, then at just the right moment, she'd change her feline eyes into human eyes, well partially human at least. The man's reaction would determine whether or not he was a wizard, or at least she hoped so.
Continuing with her 'play along' plan, Elisabeth tried to speak again, which came out in another cat noise rather than actual words. If her theory didn't work out, she'd have to run away from the man and change so she didn't get stuck.
The worst possible scenario would be if the man mistook her for a stray and actually brought her home with him, she'd have no idea what to do if that happened. She'd probably get expelled from the school or something if she never came back, this was a bad idea, but it was too late, she had already started towards the man, and at this point there was no going back.
