I took my cat carrier, too, and gave it to Val. She will put a tee shirt in the bottom of hers and mine. That way the new arrivals have a familiar scent instead of coming into a world of strange smells.
I washed one more litter box. It's currently outside on the deck, drying.
I have done all I can.
Tomorrow, after work, I will pick up my new family. Val gave me a bag of the treats she gives them, one when she gets home from work and one before bed. I have to work Friday morning. That will give them a chance to wander about the upstairs, sniffing and getting used to their new home. There will be no basement access for at least a month. There are enough places to hide upstairs. I don't need them disappearing into the basement.
Am I ready? As ready as I will ever be.
Beverage: (Ice cream is done.) Blackberry tea
