From the look on his face I think it's working well.

I haven't had to give any to Ripley for a little while but after a few days of being on it he is just the sweetest and neediest kitty ever. I really like him drugged!

I don't know how long Pouncer is supposet to get the valium but you may notice that he starts building up a tolerance to it after so long - like with people. Once Ripley is better, over his bladder problem and behaving well I usually ween him off but the vet lets me keep it on hand (and I can get more just by calling) so I can start him on it again if he starts acting stressed or upset. That way he gets a break from it and doesn't build up a tolerance or get too addicted.
