Why does my cat yowl, spit, and run, then get hungry and thirsty?
Hi an thanks for posting your question on Petco Pet Education Center, formerly Petcoach!
It is hard to say exactly what may be occurring sight unseen, but I can certainly offer a couple possibilities.
Exhibiting odd behavior randomly as you described can certainly be a sign of a neurological dysfunction occurring in the brain. Sometimes a psychomotor seizure can cause the occurrence of random odd behavior such as vocalizing, exhibiting fear or aggression, etc. These episodes may last a min or so but pet's with psychomotor seizures always do the same thing each time. A postictal period after the seizure may induce hunger, thirst, or a general unwell feeling prompting her to want to be by your side for comfort. A brain tumor could cause the onset of seizures.
There are other possibility as well that may explain her behavior. Pain, renal disease, liver disease, or other internal organ dysfunction may contribute.
An thorough veterinary exam can help diagnose Spotty as well as basic blood work and perhaps some imaging like an x-ray or ultrasound.
I hope this has helped and all the best to you and Spotty!
