My oldest of 6 years, Duckie, has what the vet thinks might be fatty liver disease. He hasn't been eating properly for almost a month now and he looks awful. Has anyone else had a cat who has gone through this? How did you treat the disease? I've read online that the treatment is force-feeding for 4-6 weeks via a feeding tube. It sounds horrendous and I'm not sure I'm willing to put Duckie through that.
