I would love to be able to explain to my cat that if we go on holiday we are coming back, and we love her and that nice lady will be feeding and petting you while we are gone.
In practice I would probably blow my chance with such useless things like-
Why are you always sick on the rug not the wooden floor?
Who is a pussy wussy then?
It's 5am and not breakfast time yet
What do you want to say to your cat and would they care?
