Outdoor Cat Enclosures 101

PrintPrint

July 12, 2011 / (13) comments

When the intermingling of species in any given household is limited by outsized immunological defenses (AKA, allergies), it’s not always gloom and doom. Cats, the most commonly re-homed or abandoned domesticated animal as a result of their allergenicity, are particularly amenable to thoughtful solutions.

 

Yes, when the going gets tough the tough get crafty. So it was that when Tybalt, one my boyfriend’s cats, couldn’t leave any surface in his home unmarred by his urine, and re-homing to my third bedroom seemed preferable to the alternatives available, I had to confront the realities of my son’s asthma — creatively.

So how do you keep cats happy in a household when keeping cats at all seems like a really bad idea? Here’s one solution most people never consider: Build them an outdoor room!

Mostly because of my son’s allergies and asthma, but also because I don’t like the idea of keeping cats out of doors (safety first), outdoor cat enclosures have always seemed like a great (if imperfect) approach to a very common problem. In fact, I’ve always wanted one. I even asked for one for Christmas once (and never got it). But I’d never had a chance to really need one until Tybalt’s crisis.

But it wasn’t just Tyb who’d been living in a veterinary hospital for weeks now. I’d been jonesing for a spot to put Ralphy, my fat little three-legged, serial urinary obstructee. The two would make a nice pair. While Tybalt might temporarily balk at being forced to share a space, Ralphy would just roll over and go back to sleep. Yawn!

So here’s what we did: We decided to utilize my third bedroom, a wasted no-man’s land where the detritus of the past ten years went to roost and my knitting supplies multiplied like hamsters in their plastic boxes. This area, once cordoned off from the rest of the household’s air handling unit (except to accept inflow) would serve as an indoor home base (not always feasible for owners, but luckily doable for me).

A judicious application of weather stripping on the interior door and a small perforation in the window for a cat door served well. Air came in through a vent and trickled out through the window. Magic. Wasteful magic, AC wise, but magical nonetheless.

Then came the hard part (apart from having to actually tackle the organization of what had essentially become one large, disorderly closet): designing and building the enclosure.

Actually, the design wasn’t too terribly tough. We had a house’s structure and some existing wood to work with. Both informed the design as much as anything else. So we built an enclosure with two-by-fours and some fencing under the eaves, connecting the third bedroom to the space via the cat door in the window.

Add in some shelves, a bird feeder a few feet away for our kitteh’s viewing pleasure,  and a solid weekend of work later — voilà — it’s a home.

Tybalt was first in. He’s been there 24 hours and so far so good. Though he’s one of those hidey, scaredy cats, he’s been out and about. He loves hanging out on the shelf right outside the cat door, and he’s been climbing the shelf habitrail we built on the inside. And though we still need to build more shelves into the outdoor area (we ran out of brackets), it’s already more than serviceable.

Take a look and see if you don’t agree:

Here’s the interior, with the cat door built into the window, the shelves depopulated of all their junk and staggered just so’s cats can use them as their hangout. My reading spot (an inexpensive bean-bag chair and ottoman courtesy of CB2) will doubtless double as a giant cat bed for sleepy Ralphy.

And here’s the exterior, jumpy-shelves, ramps and cubby holes to be added (and wood soon to be painted so it "hides" into the house a little more than it currently does). At the last minute we added in a small slightly rusted aluminum table I was going to put by the side of the road. This way someone can actually hang outside with them if they so choose.

The litterbox, you ask? For right now I’ve added two of them: One indoors and one out. Come a week from now, I’m hoping to be able to keep them both outside. I’ve chosen to use disposable boxes with clumping feline pine for compostability. It’s a little pricier than other alternatives but hopefully well-worth the extra expense.

But what if Tyb starts up with his pee-pee habit again? Everything’s pretty much plastic in the third bedroom. And — guess what? — if things get really crazy the cat door has one-way lockability in either direction. Not my favorite solution but one that’s built into the design already.

So what do you think? Have you ever thought of doing something like this? If so, and you never thought it would be doable, consider it inspiration for all you homeowners. Re-homing is not always the preferable alternative, not when you have a house to do with as you will.

My house Bengal has her own "Catio" and loves going in and out. We had the cat door installed when we built our house and then added on a 4 x 20 foot covered run against one entire end of our house for the cat. We added in logs wedged in for climbing and a bench for sitting and let the grass grow for munching. She even catches mice!
Her cat box is out there as well.
BTW, instead of spending a fortune on "Feline Pine", go get stove pellets or horse bedding...same thing at about a 10th of the cost!

Catios!
by pedrolobo on 07/12/2011 03:04am

Excellent idea! My girlfriend's cats love the catio she had built--plenty of outdoor time without any of the risks!

There are lots of examples to see at (sorry, shameless plug) her site, Catio Showcase (http://catioshowcase.com/).

Mikey, my best friend/cat was born deaf, I realized this when he was about six weeks old. I have always tried to keep my cats indoors but when Mikey came along it became a must. We live in mountain lion country and even cats that can hear stand little chance of surviving up here outside.
We decided to build the cats a cat enclosure. It went out a window of one of our rooms and we built a tunnel that took them out to the enclosure. Here is a pic of it if it shows up.

We are now involved in a new structure 8 years later...Mikey wants to climb a tree so we are building one so he will be able to do this. He's a little spoiled yes but after being the best friend he can be to me for 8 years, he has it coming.

Florida vs The Midwest
by TheOldBroad on 07/12/2011 07:17am

I would hesitate to create an outside enclosure due to weather extremes in the Midwest. Also, with all the vet visits, it would be even more difficult to catch today's patient.

However, bully for you! The kitties are going to love it.

What modifications do you think you might make as the kitties age and don't jump as well?

by Dr. Patty Khuly on 07/12/2011 02:04pm

Modifications? Oh yeah ...

Who needs age? I just added the three-legger. Looks like he's going to need to lose LOTS of weight (he weighs 14.18 pounds!) because he's having a really hard time getting around on only three footsies.

Although we made each sequential jump no higher than 18 inches, fat little Mambrú is unable (unwilling?) to navigate the narrow shelves. Some of them rattle so I'll have to fix that. But mostly it's their slipperiness, so I'm going to add simple wipe-able no-slip pads everywhere.

Weight loss should do most of it, though. He's been living in a hospital for two months (where everyone loves to spoil him with treats and he *never* moves) so all this space should really help.

by TheOldBroad on 07/12/2011 07:37pm

Mambrú is obviously waiting for valet service.

I had a very spoiled kitty (mostly due to all of her maladies and I babied her) that was fully able to go upstairs at bedtime. Little Emma Jean would watch everyone else fly up the staircase, but she would sit at the bottom of the stairs and cry. So, of course, I carried her upstairs to bed... every night for several years.

good idea
by alice in lala land on 07/12/2011 01:46pm

keeps cats safe.. but cat pee all over.. no thanks.. one question why do some bloggers spell kittie "kitteh"?

by TheOldBroad on 07/12/2011 07:31pm

"Kitteh" is part of LoLSpeak from I Can Has Cheezburger (icanhascheezburger.com)

we've got one
by cesg on 07/13/2011 03:34pm

we built it a few years ago for the old house and moved it to the one we are currently in.

http://s78.photobucket.com/albums/j98/julia9874/cat%20enclosure/

Unfortunately the kitties haven't gotten to use it for a while because we had a flea covered groundhog move in under the shed next to the cat room and dig under the walls for another escape route. The ground hog is gone now (thanks to a feral cat I was fostering and the strong smell of her stool) but I'm still hesitant.

My friend also has one. Her's starts on the second floor and goes up to the third and on to the roof so her cats have a bit of protection from ground animals and fleas and the such. I've always loved the idea but I couldn't convince my husband to go for it.

Our "Catio"
by Gretchiesmom on 07/14/2011 02:45pm

Last August hubby and I set up a catio/outdoor room for our cats using a 10' X 10' chain link dog kennel as a compromise to the inside/outside cat dilemma. Our cats LOVE IT and it gives them another 100 square feet of space to hang out. We pushed the kennel up next to the house, and used the side of the kennel that would be next to the house as [most of] the ceiling, and then added a strong, inescapable shade cloth over the top. It's on our concrete patio. They have a kitty door like yours that they use any time they want some fresh air or to watch the birds. We live in a rural area, so there is usually always something for their entertainment. We furnished our catio with some old redwood patio chairs, an old wood table, some shelving units, a long board for a catwalk, plants and mobiles. A large flat-topped dog house holds a huge litter box, and there's a standard box too. I am trying to come up with a way to provide cool water out there, but right now they just step in the house to drink. But it is secure, was fairly inexpensive, easy to keep clean, and the cats do love it.

3rd bedroom
by teri on 07/17/2011 12:15pm

My cat lives in my 3rd bedroom due to FLUTD issues. She has run of the house when I am home, but in "her" room when I am not. Would love to build her something like this, but unfortunately her room is on the second floor.

Love your solution for the problem cats.

2-Story Catios
by Gretchiesmom on 07/18/2011 02:03am

I've seen photographs on the net of 2-story catios, but they would be more challenging to build. It's something to look into though if you have the space.

Outdoors area
by Gypsykatz on 09/23/2011 10:54am

I own a small house and I have fenced in a portion of the back yard to include the backdoor and my back bedroom window. At the top of the fence I have attached a smaller section of fence that is bent in toward the yard and kinda "floppy" - my calico can climb even a wire fence and this unstable top keeps her from climbing. Right now she either goes out the bedroom window and down a step ladder to the yard or if she thinks the younger cat (came to me as a stray hurt, hungry and asking for help one morning in March) isn't by the backdoor she will go in and out of it. I have a shelf and ramps that a friend of mine made that I am in the process of painting and then will attach underneath the bedroom window. I am hoping this new set-up will make my tortie feel easy about going out. My girls love to help me in the flower beds and sit with me on the throw rug while I read in the sun.
