cold/not eating

Any advice/input for a cat that won't eat? He's had a cold for a few weeks and hasn't been eating for about 1 week. Other than a few temptations treats, juice from canned cat food and a little turkey on thanksgiving, that's really it since last tuesday. He IS drinking water as usual and is peeing.

I've tried a few other wet cat treats but he sniffs it and that's it. Today I broke down and forcefed him 'friskies lil' gravies' liquid treat via syringe. I was surprised he took it better than I thought, not running, trying to bite or anything. I didn't even hafta hold him firmly in place.

Other ideas to entice him to eat would be greatly appreciated!!! :-)
