Dunhill has recovered, though it took a while to get back to 100%. I am going on a trip, at the end of this week, and I am taking them with me. It's just five days, and I'd normally have my cat friend (who loves these kitties nearly as much as I do, and always refuses pay) check on them every day, but she's also going out of town. Dunhill and Silver act like three miles in the car is murder, so I'm sure 450 miles will be just fine. I have bought new carriers that are made for the car and have seatbelt attachments and pads. I'm assuming they will eventually settle down?
Also, my orientation for volunteering at the local SPCA Kitty City (where I got my two monsters) is set for September 7th. I am excited about it!
