Good to hear Riley survived:)
I gave Fletcher a half dose (1/2 25mg tablet) last night. At first, I thought it hadn't started to work until two hours after I gave it, because about an hour after, he jumped up off the couch and ran to the window when some people walked down "his" street. He was sleeping pretty soundly before that, though, so maybe it started earlier. The rest of the night, he was pretty zonked, walked kind of like he was drunk, but didn't seem distressed, and is fine this morning.
So, maybe I need to give him the whole pill? Maybe start earlier? I am still full of questions about what to do. sigh
