This is concerning that you can't get Lissy to eat anything, and I would take her into a vet immediately. It could be that she isn't one the correct dose of thyroid medication or there is another medical problem going on with her. Leaving cats who aren't eating is very dangerous, as if they don't eat going on 72 hours, they develop a fatty liver which is fatal without treatment. The vet can give her an appetite stimulant, and can diagnose why she isn't eating. Please take her into a vet right away. I hope this helps!
