I enjoy animals. Always have. I grew up with cats, dogs, hamsters, gerbils, turtles, fish in bowls, fish in aquariums...you get the picture. They make me smile, give me companionship and I view taking care of their needs as my part of the relationship. I don't have a dog now because I don't have the energy or mobility to walk a dog everyday, multiple times a day. Nor do I have access to a yard that would also allow the dog to roam & be fit and enjoy his/her dog life. I wouldn't knowingly compromise an animals needs for my own. So I have cats, two currently. I've had more and less at different times in my life. Two is good for me now.
I would have been in a van a few years ago if I didn't have my cats in my life. Temp extremes are even more difficult to deal with when your animal is a cat versus a dog. Dogs are easier to leash train and are more accepted in venues if temps are rising and inside the van isn't comfortable for them. At least that's my thinking. Working out climate control issues has been my .ain priority. I can add more blankets in the cold or go to a movie, mall or coffee shop in the heat of the day to get some air conditioned relief. So my animals are important to me.
All that being said, living a life with dignity within my limited means and health issues and having experiencs and being with people that enhance the joy in my life is also important to me so I've turned to vandwelling as a viable option. I'm just starting the process of making my 20 year old conversion van livable for me and them. I've been leash training the cat that has more get-up-and-go in him. He's younger and that's just his personality. He's the one I may have to rehome if he doesn't adjust well. It would be sad for me but may be better for him. Only time will tell. The other one I found in a field as a kitten and has never been an explorer of the outside. Doors and windows have been left open and he just sits by them. The few times he has ventured out have been just enough to seem to remind him that inside is the place he wants to be. I think he'll adjust just fine to living in a van. Both cats were with me when I drove across the country in a Rav 4 i think and after the first day I let them out of the carrier. They were much happier out of the carrier than in it. The rest of the trip was fine. They also traveled from California to Oregon with me just fine, again outside their carrier. They seemed fine then also. I'm really torn about the carrier. I know they are safer in the carrier if I were to be involved in an accident but they seem so distressed inside the carrier and much calmer when able to be less confined and see around.
They will both be chipped, up to date on shots and have updated collar tags when I move them into the van. I've read and studied ventilation threads on this website, especially anything Sternwake has contributed to, for my ventilation plan. That plan will be adapted as needed for their comfort as well as my own. Solar is not in my budget currently and I will be local and doing urban stealth for at least a year or two. I am also planning on living in versus living out of my van. I am in a temperate climate locally. This all plays into my ventilation decisions as well.
So not a lot of actual experience with mobil living with cats but at least I can explain some of my thought process to you. As with everything, how you prioritize your needs and what your actual needs are versus mine will probably lead you to different decisions. As I do the actual work to my van and move in I plan on updating the area on traveling with pets because I was disappointed with how sparse it was.
