end of life

This is a very tough post to make, so please be kind, but I need some opinions on the quality of life of my guy. If anyone else has a Dragon with some very specific, specialized caretaking requirements, I'd appreciate some insight, if you can offer some. Or if you've had a quality of life...

I have an 11? year-old dragon who has really slowed down over the past few months. His eyesight is terrible and he will not eat on his own. We have been syringe feeding him Beardie Buffet, Grub Pie, or Critical Care. He will usually lap it up pretty well for me, but not really for anyone...
