<human>: Provide a brief overview of the text.

My husband and I have two pets, a dog and a cat, and we recently moved to a new apartment. At the old place, our cat was free to go outside on our balcony since we lived on a 3rd floor walk-up and there was really nowhere for him to go. Our new place is on the ground floor and our patio is not fenced so we can't let the cat out in case he wanders off and doesn't come back. After moving, he slowly started eating less and less and has now stopped eating altogether. We took him to the vet and they hit me with a barrage of mostly incomprehensible gibberish. What I got out of it was "Your cat is very sick". He is jaundiced, which obviously isn't good. From what I've read online, he most likely has fatty liver disease from not eating. Anyway, the vet recommended we do a battery of tests including an ultrasound and keep our cat there for a few days, which would cost somewhere in the region of $1,600.00. I love my cat very much but we simply can't afford to pay that much. They have given me an appetite stimulant, an amino complex, a cat pheromone diffuser and some high protein intense food to feed him. I've been feeding him with a syringe but I'm basically forcing it down his throat (it doesn't seem like the appetite stimulant helped at all). At least he's not dehydrated. Does any one have any recommendations for things I can put in the food to make it more palatable or anything else what would be helpful?
