Betty sounds very sick at the moment, and based on her symptoms, she should see a vet immediately. Without seeing her in person, I can't say what's causing her fever, lethargy, weakness, and lack of appetite, but she could have a systemic illness or infection causing it. She does need veterinary care now for it, so please bring her into a vet right away. I hope this helps!
