So, today’s Widget update part 1:
Ok so, diagnostic summary: It's not likely a polyp/tumor or cancer in the brain. Her EKG and BP are normal/normalish so it's not a hypertensive/cardiac event. Her diaphram is a bit more upright than one would expect, but doesn't seem to be a problem. Her airways are pretty decent for a cat who's had asthma for a long time. Her thyroid came back normal. Radiology showed that her abdomen looked good, kidneys, bladder, liver, etc all looked good.
