Q. I don't have the money to find out why my cat suddenly lost interest in food. What can I do?

A. You should contact the closest dog charity or free vet clinic in your area in order to get some financial help toward the treatment of your cat.
According to this symptom, he needs urgent help, a cat that stops eating without a visible reason is usually suffering form an internal condition and needs to see a vet right away.
There is unfortunately no way around this and nothing you could do at home to help without knowing what is the problem. For that you need a diagnosis that only a vet could provide you.
