Just in case the same with dogs. My cat stopped eating for another reason and developed a fatty liver syndrome. The clinic I took her to strung me along for two months with no results. Thankfully the next vet immediately said I don’t see signs of cancer, tested for thyroid or liver-found to have the liver problem and Then only had to go 5 times for a repeat of, drip to hydrate her for 5 min, and a gel He put behind her ear (forget the name) which stimulates appetite. At first she would eat the first day and then it sliwed down, but by the fourth time she was eating normally and took it up to fifth time to be safe. She’s back to normal and healthy and happy. I hope this helps and I really would like to know if you succeed. It’s usually more simple then they say.
