This is an important discussion.
I have been worrying a lot about how to leave my cats for even brief periods of time in our RV, once it's usable. I have no choice about moving into the RV, this is what we have,and i can't give them up.
Still at my parents while the mechanic works out all the bugs. A few days ago my partner came down with what is probably Norovirus (which I now have,and wow, is it miserable!) But since the symptoms can sometimes also be Covid, I scrambled to find a place to test and give him the new antivirals, if necessary (At home and the PCR tests were negative, in the end.) It ended up being an endless goose chase because we weren't told important info after making appointments, and were gone for hours. What would we do if we were in the RV and it was really hot out and there was no shore power? Can't leave a generator running,can you? I would consider cat boarding, but lots of places don't offer it.
I'm hoping I can find caravans to camp with where we can get others to cat sit and such. I can't imagine trying to work a job away from the RV and having pets. As for UK's proposed solution, people do crate their pets all day, which I can't even imagine. I agree with UK that it might be the lesser of two evils, but I also know I couldn't do it.
Maybe the answer really is community. Finding people who you can trade pet sitting duties with. Or coming up with community pet sitting services for a lower fee than doggie day cares and cat boarding?
