Lazy Daze Owners' Group

Cats, we have 2.  One is bold and in your face.  The other, like most tortoise cats, is more sensitive to notices, being bothered by her sister, us moving around, etc. so she likes to have her own spaces where she is safe.  To travel they like to be under the passenger seat in the cab (pic attached, you can see two cat butts sticking out of the seat).  It took one or two trips, but they have the routine down.  They quickly settle down after we stop (which means come out and be cats) but sometimes they know we are just stopping for lunch and they just stay under the cab seat the entire time.
We do a cat count before we leave any area just to make sure they are with us.

They are great fly and bug catchers.  They like to investigate anything brought in, stare out windows, lay around, and bug us for petting or food.
Many people say their cats love the bed over the cab, ours will go explore up there (this is our storage area) but don't spend lots of time up there, but depending on how your cab area is configured... for ours they climb up the blanket hung between the cab and the coach.  We have not tried the nail caps, but we do work to stay on top of what is allowed to be scratched, bitten, or wrestled with (their toys) and what is not (furniture, our stuff).  Our bold one loves to chew tape (all kinds) so we have to watch that, she also chewed thru a headset cord I recently got - just a cheap one but with such nice spongy cord material she couldn't resist.  They need toys, scratching areas, etc.  Not so important for shorter trips, but for longer ones a must.

There are sprays like Bitter Apple spray that keeps them away from cords/things they like to chew.  One cat wasn't phased by that so we found Ick at a pet store but I can't find a link to that.  It was worse, but if it got on you and in your mouth (even days later), it was bad.  [We had a cat at one point that would sit at my desk/on my lap and check on the phone cord I was talking on, the computer mouse cord, any electrical cord, etc. etc.  Days later, if I touched the cord I would get ick on my hands, wipe your mouth and ... well Ick. ]  They don't like citrus or vinegar or strong smells like tea tree oil either so that might work.

You need to watch where they go - our brave one likes to hang out inside cabinets, the shower, join us in the bathroom when we are there and has gotten shut inside the bathroom a few times before she learned to quickly run out when we stood up or faced the door. But in the middle of the night if the door was left open a few inches I will find her sitting on the toilet or in the shower - who knows why.  She liked the cabinet under the oven best (the door didn't shut securely so she could open it).  We didn't use that cabinet and one day I said I better check that out and in the back it opened into the tray that held the electrical cord curled up in (so the cat was laying on a 30 amp cord).  It immediately became a no cat zone and that latch was fixed.  So like a regular house, you have to watch curious cats to make sure they don't go where you don't want them to go.

Same with watching the doors and windows as some cats are out in a second if given a chance.  We have to watch our bold one even though she knows not to go out (current cats have always been indoor only cats).   We forgot last week and left a cab window open in the afternoon and DH came home that night and found the bold cat on the hood of the cab, he yelled her name and she ran back inside.  She was is the same in a brick and stick home, the evening of a move in she explored the fireplace (new for her) and standing on all 4 paws suddenly whoosh she was up the chimney like Santa Clause while we frantically split up one going outside in case she made her way to the roof, the other trying to peer up the chimney - it turned out she had jumped onto a shelf just above the fireplace opening.

Many people give the cats a designated cat area - we have a few of those, the main one being the cab area when we are parked as we rarely go up there when parked.  But we place cat beds and cat carriers around so they have places that are theirs so they don't get kicked or bumped as we walk around.  We recently moved to collapsible cat carriers and leave them out also for a hiding place and so the cats are familiar with them when they are needed.  Oh, and we buy only fluffy soft cat toys so when we step on them, especially the middle of the night, no yelling happens.

Lots of people have cats in their RVs.  For a short trip (2-3 days) I would leave them at home as I could leave food out for them, but longer trips I would take them with me.
Give it a try and give them some time to adjust (like a couple trips, maybe the first one a short drive and a longer stop).

Scratching items are tough for us as our cats don't like Sisal rope (the common thing most cats like) nor cardboard (we tried several different shapes and sizes of both).
Their favorite thing to scratch on is fake leather (e.g. vinyl couch), if that is not available carpet works. 
So for us it is custom building something for them (thin board covered with batting then the scratching material) and securing that both vertically and horizontally (they like to scratch both ways).  And that means finding a place to put it on a wall and the floor (for us the entry way seems to work as that cabinet wall is mostly blank, the rest are all in use).  Just be aware what they would get if they reached a little higher or to one side (protect things you care about like a wire/display for a device like the battery charger).

So it depends what your cats use at home - vertical or horizontal scratching, and what kind of material they like to scratch. 
I would stay away from any scratching pole with a stand or box or bulky item - it just takes up too much room.
There is all sorts of scratching mats and hanging scratching mats available. You notice they are all sisal so they don't help us.  I would also pay attention if they are scratching off the mat (e.g. really getting the carpet or cabinet), going thru the mat to whatever is behind it (cabinet, flooring, etc.) and adjust as needed.
Sometimes they will just try out something new to see if they like scratching it.  Luckily our cats are not fabric scratchers (and our front seats need reupholstering anyway) so we don't worry about the occasional scratch but try to keep an eye out and redirect them to what we want them to scratch.  Many people cover all the upholstery right away to protect them from pets and people (spills, etc.) so they stay looking nice for a long time. 

We got some soft mice and fish flop  recently at Target I believe.  Check as many of the small mice are really hard cardboard.  And be aware of the pieces they will tear off and potentially swallow - I like no separate eyes/ears but that is near impossible, so I go for all cloth parts or at least feathers and no beads/hard parts.
We have used soft balls in the past.  And shoe strings are always great.  I would stay away from things on a pole (just another thing to find a place for), or hard toys (their favorite toy in a regular house was catit circuit - they even slept curled up by it, but there is no place to put it that wouldn't get in the way and stepped on. 
We have used crinkle balls in the past and they are ok (not bad if you step on them barefoot) but soft things are better so that is our new rule as small soft squishy things are barely noticeable if you step on them.

We just got this gator scratch toy as our tortoise like to take a small rug and roll around with it.  So this fulfills her need to wrestle with something other than her bossy too rough sister but she doesn't use it for scratching.  I don't know if she cares about the crinkly noise but it works well if we step on it and she moves it around a lot and we hear her wrestling with it.

Like many cats their favorite toys are things that get dropped like q-tips, bottle caps, thin strips of plastic off bottles, paper bags, coins, etc.  And for them it is fair game to knock those things off counters/tables, steal them out of cup holders, etc.  But overtime I keep those off the floor as I would rather something soft instead (q-tips are soft but I am sure there is a rule momma cats say about don't run around the RV with a q-tip in your mouth, similar to the human moms that say don't run around with a lollipop in your mouth).

Cat mats/bed/carriers... We recently got these cat mats and the cats love them (the first hour each of them spent on it was an hour straight of kneading it).  Many people use a flat mat rather than a cat bed with the lip on it and I am starting to lean that way except one (or two, one up high, one down low and hidden) if they want to cuddle together.  Flat mats can go on the dash, the bed, the seats up front, the foot areas of the front cab, etc.  But our cats have leaped and knocked beds off making them not usable and it can take us a few days to realize that.  Our cats are fine on the dash without cushion (still young) though some people fasten something to the dash for their cats to soften it.
We got these cat carriers recently and like them a lot.  However, while they are very sturdy and well made one is now showing some issues.  I am pretty confident from reviews that the company will stand by them (they are only about 3 months old) but I just sent out the email yesterday so I can say for sure yet.  The cats like them but one was starting to scratch the top which is why we got the plush mats to go on top of them.  They really like laying there on top of the carrier but also inside too.  We leave them out as they are not really crate trained so if we need them in a crate they will be more comfortable knowing the crate and we have room to have them out.

Oh, if you are startled because the RV is shaking unexpectedly, it could be the wind or it could be the cats playing.  Amazing how much jumping from above the cab/a countertop and down, charging from one place to another, etc. can rock the RV.

So far the only issue has been the Genny, I think it needs a new fuel pump...hopefully wont be too hard to swap.
