Please pray for my cat Sugar!

My cat Sugar abruptly stopped eating; please pray for him to start eating again. I took him to the emergency room and the doctor wanted to put him down immediately because he was having a panic attack; she didn’t even give me fluids to give him through an IV for when I got home with him. I am taking him to the vet this morning and asking for him to be throughly tested for illnesses and infections as well as for IV fluid to take home with me so that he can stay hydrated and nourished.
