How is his vision and hearing? I had a foster cat that was doing that, and it turned out he was blind and deaf (also had a brain tumor ). Alex would get stuck in the strangest places, and just wail. It was heartbreaking.
To be honest, I think some drastic has happened since those last seizures. He is agitated all the time, he walks into things, walks into corners and can't figure out how to get out, trips over everything, spilling the water bowls constantly, gets into rooms and can't figure out how to get out and somehow manages to shut the door of that room and whines constantly unless I am right there to be with him. I have spent most of the last two days on the couch trying to keep him calm. If there is not a beginning of a change today, I am afraid I may have to make the decision I don't want to make. But this is no life for him. When he is not sleepnig, he is pacing and whining, lost and confused. The valuim only seems to increase the agitatedness and from talking to the vets there is not much else to do for him.

So pray extra hard today because I am at a point that I know that he cannot go on this way. I love Snoopy so much adn it breaks me heart to think I may have to let him go.
