I have a orange and white tabby ... she is 14 pounds of chunky love !!
If we take a lonnnng trip she needs to come with us, but Vince is dead set against it (I really don't want to take her either) I bought her a soft cloth dog harness (cat ones are to small

).... she seems to only go in reverse when she has it on or just drops over on her back feeling she can't walk with her new iron suit on. I took her out to the rv .... she of course may be fat but she is ozzie fat so she proceeded to find every nook and crannie to try and squeeze into and hide .... not a good thing. Vince still says no but "
we" are now talking about removing the euro chair we don't use and putting in a large soft nylon folding dog crate to keep her in while on the road.
I can see that her joining us would be a problem, a continued escape try at each stop, although, if she has the harness on, she would slowly walk in reverse into the couch instead of running out the door and then fall over, purring super loud through the entire event (she is funny to watch) !!
We can leave her home for three or so days and she is fine with extra food and water, but we would like to travel out west and be gone for a month or more and being as we are in hurricane country we would have to shutter the house down tight and I would never leave her and would not want to put her in a strange boarding facility.
Has anyone actually traveled with a cat and been sucessful ???
