When the family Siamese was PTS at 19 1/2 (mom had taken him in a month earlier, but brought him home, and cried...she just couldn't), it was apparent that he had had little strokes for some time. Nothing that one could 'prove'...but during the last trip to the vet, he stood up in his carrier the whole way. I sat outside in the sun with him, opened the carrier - and he never even turned his head....just stared at the back of the carrier...

I know Omega 3 can help with dementia and strokes; is there a mild tranny that his kidneys could handle, or some Feliway, for the OCD?

Good that he is a whole pound heavier...I hope he regains some well-being.

Give him a hug for me...
