thanks Kit. And hugs back for you and Esther. We bought that ramp awhile back so he can still get up on our bed at night, and now a couple weeks ago we bought him a raised-up food dish so he can eat more easily (he was having trouble eating from a normal dish his head would bob up and down after each bite so he could swallow, it looked so uncomfortable for him) and that has helped. Part of me wants to do everything possible including all the expensive tests, etc. but part of me says if he were a kitten that would be one thing, but he's 14. He's not falling down when he walks, but we can tell his legs are weak or hurting him when he walks he stops and sits every few steps. I wish there was a magic sign to tell me what to do.
