So sorry for your loss Ladybug. We have never spent a night in our camper over the last year (20,000+ miles) without our quickly aging, 16 y.o. tabby cat, Buddy. It pains us to see his physical abilities deteriorate to the point where we sometimes have to help him jump up to his little bed on the couch.
We just did a 25 day trip with him and had a couple of discussions about what it would be like without him there next to us... can't imagine it. So much of our time out there revolves around his needs (food, quiet and clean litter) and that keeps us grounded so to speak. He truly is family as I know Pugsly was for you.
