Hi Sheri,
Your cat may have an upper respiratory infection and a sore throat or tonsilitis. When you say you noticed a 'lump' in her throat, do you mean you see a bulge in her throat, or you can feel something there? Cats' throats have something normal which feels sort of like an adam's apple; is this what you're feeling? It's also possible that she swallowed something she shouldn't have, like a bone or a piece of a toy or a pin or needle. Is her breathing normal? Does she go outside at all?
If she's not eating or drinking she will become dehydrated which is very dangerous. Do you have an Emergency Animal Hospital nearby? I think you should bring her in to find out what the problem is and have her treated.
Please update me on her condition? Thanks!
