Opalescent, no idea, I'm afraid. My cats "get the rips" at about 7-8pm. Does your vet have any recommendations? Hopefully, you find something that works for you.
CW, how does one teach a cat or dog to avoid cars? To not curl up in a warm car engine on a cold day? It's great to say "You should" but maybe I should be able to speak 'cat' as well, then. It's just as achievable.
Probably best to just do what I've been doing, and keep my own eyes open in order to avoid animals that run into the road.
