No, so a vet trip is in order. If it is thyroid, the vet can check that, and likely correct it with medication.

Brain chemistry is a tricky thing - the few times in my life I have had to take prednisone, for example, I was hugely hungry all the time, regardless of the reality of what I could possibly eat, or have just eaten.

To the vet with kitty, sorry!
