Cats quckly learn the litter box. While traveling, I have only seen one cat that actually stayed near the RV without being leashed. Many cats have been abandoned by their owners because they run off scared and can't be found.

Our boy was a stray, although only about 10 weeks when he adopted us. Immediately once introduced to the litter box, he started using it.

We would leave him locked in the bedroom of our fiver while we traveled. We noticed he would not use litter box or eat. Then three times after a several hour drive, he wet our bedspread. We took him to a vet in TX as we thought he might have an urinary tract infection. She said he was healthy and it was probably pyschological! Great! He was mad at us.

We now keep him in truck with us. We put litter box and his carrier on back floor. He likes to lay in carrier and uses the litter box. Evey so often, he will come up and sit on my lap to look out window or he will lay on the center console. He has become quite adapted to traveling and seems to enjoy it.

Chances are your cats would adapt also.

Most Campgrounds have an all pets leashed policy.I agree with the others, start working with them now.Even older cats can be litter box trained.Try some of the covered ones that give them some privacy and that may help( I read that somewhere).Welcome to the best forum on the internet.

If they are going outside, they need to be leashed.  Also, make sure you know where they are when setting up the rig.  I know of one instance where a cat met a slide out with disastous results but I also know several people who travel with Cats, keep them in the rig all the time and everyone enjoys the traveling.

Our cat was an indoor/outdoor cat before we hit the road. So no issues with the litter box. She loves to go outside on her leash, but it's not like walking a dog. It took about 4 months for her to learn how it worked, but now after over 2 years, she is an expert. Usually, she's on a stake with a 16 foot retractable dog leash, the kind that pulls out and retracts automatically. She's an expert about winding that through trees, and fences, etc and not getting tangled. The slight pull of the leash tells her which way to turn etc, and the constant slight tension doesn't bother her a bit. Loves to chase geckos, lizzards, bugs and other little critters. My wife really loves having the cat with us. But after trying for 6 months to have her ride in the truck as we go down the road, she now travels in the 5th wheel, and we're all happier. Has her own hidy hole under the bed for travel, rain storms, thunder, strangers, etc.
