It was moi, Nana !!

Didn't work too well; William meowed 800+ miles anyway. But it was not a "knock out" sedative - one just to calm him. Guess it wasn't enough. However our cat was 15 and had lived in the same house all his life - it was a traumatic change (100% indoor cat). Took him a month to adjust. Maybe if it's a total sedative, it'll work better for you.

Good Luck !
