Up and down like a toilet seat

Lilith has been doing really well on her new meds, but this morning, she refused to eat (so her meds didn't make it into her system). She had noticeable trouble walking, and is panting a lot. Her food is down, and I sure hope she eats it really soon. At this point, every time she refuses to eat, I worry (for obvious reasons, I think). Sigh...
