Franklin is a weird cat
Not at all! Quite normal. Keeping them separated is safest for Mom cat. I think a few hours should be enough.

You can buy some Composure Chews and give those a try. HE is the one who would take them. This may cut down on the amount of time you have to keep them separated.

I bought mine from Amazon.com, for 2 of my dogs when they see the groomer; or when I have to groom them.
