Introduction: Cat Castle

Picture of Cat Castle

Build a two story cardboard box castle/hut for your cat! Everyone knows you don't need to buy them toys because they will play with just about anything! This thing doubles up as a play area and a place where your cat can sleep. As a bonus your cat will like being up high. I set myself a challenge for this project to use the least amount of sticky tape as possible.

Step 1: Materials and Stuff

Picture of Materials and Stuff

Craft knife
Sticky tape (Not much was actually needed)
Cardboard boxes (Same size helps)

You don't really need all of these items as it's not going to blow up if you make it a different way. You might as well experiment a bit!

Step 2: Start Planning and Cutting

One box is used for the first story, one for the second story and the third is for supports and add-ons.

So, grab the first box and start out with cutting a hole in the side where your cat can enter it by just walking in. You can leave a flap for a door or just cut it right out. Fold the bottom flaps of the box and cut the top flaps off as seen in the photo.

Start cutting out some rafters to support the second story. Mine went from one side of the box to the other and protruded further by about an inch or so. Make sure the rafters areat least a few inches thick to support the weight of the cat sitting above them on the next story. The rafters are linked together so that they support eachother and share the weight. To link them like this in the photo, you will need to make a cut half way into each rafter so that you can slide them together. Make sure to measure the cuts so that you don't bend the rafter too much - keep them nice and straight.

Just study the photo to get the idea...

Step 3: Stair Case!

Apart from just jumping up, how will the cat get up to the second level?! This part is fairly optional but is good if you decide to make the top story a sealed off sleeping area.

I cut out two triangles of the same shape and size with a right angle so the stair case can sit against the box wall. These two triangles are each side of the stair case. Seven or eight stairs will get your cat up there but that depends on the size of the boxes.

You need a bit of patience with making the stairs as it can drag on a bit. They came out surprisingly sturdy though so give them a go. Just make sure to study the photo to get the idea of what it will need to come out like.

Step 4: First Story Complete

If you managed to follow up until now, your castle should look something like this. Before starting the second story get the cat and see what it thinks of it's under construction castle. It may take a few looks before it uses it. Kittens will most likely just get straight into it and annoy you while you are building it. At least they like it, right?

Step 5: Second Story

Pretty much what you see here is what needs to be done...

Using that thrid box, cut out the flooring for the second story and the perch/balcony. You only need enough tape to stop it from moving. The support for the floor is in those rafters!

Grab that second box and put it on the top. Use a few bits of tape to hold it in place on there. I cut another doorway for the cat to get out onto the perch/balcony. The cat will probably prefer to jump up onto it once it's done so make sure it holds the weight if you decide to make one.

Step 6: Finished

In the photo you will see what the end product should similar to. The height of the castle is about 3/4 of a metre high but you could really go as high as you wanted I guess. I put a cloth inside the top story to pad the flow a bit so the cat can sleep in there and she does! Sorry if I didn't go too deep into details but you can do what ever you want, really. Just experiment and see what you come out with!

I didn't make one of these but it inspired me to make a cardboard house for my cat

This is soo cool! Here's a photo of my cat. He wants to say thanks! He loves napping in it!

narex (author)catlily2016-07-10

Thanks cat!

whirlpoolisfabulous (author)2014-09-28

So cute,I actually tried to make Elsa's castle with this and it looks amazing!

That sounds epic!

DeejayJeanP made it! (author)2015-09-07

I tried to do it ! I think I succeeded haha. No second floor for me, because I couldn't find another box that was the same size. I used your base, which is genius btw haha, and I built up from there. Cut out a few "windows". As you can probably see, no sort of measuring was done here haha, as basic as it could be. I used tie-ribs (I don't know if that is how you spell it) to hold everything together, which worked wonderfully, and also looked pretty cool. I used some bubblewrap on the ramp up to the first floor, put down a soft mat for little Ikki, and as you can see, she loved it, and fell straight asleep after 10 minutes haha. I might try adding another floor later on.
Thanks for the tutorial, I made this in about 1,5 hours, with just some scissors and tie-ribs :)

narex (author)DeejayJeanP2016-07-10

I see yep. Nailed the platform! Zip ties were a good idea.

margaritamffb made it! (author)2016-02-11

I took your idea and created this beautiful play gym for my little kitten ? thank you so much

narex (author)margaritamffb2016-07-10

Nice one! Cat should have fun exploring that!

jewelzeyes (author)2016-07-09

Is regular cardboard sturdy enough to hold a 10-15 lb adult cat? Esp on those stairs?? Did u use anything to reinforce?

narex (author)jewelzeyes2016-07-10

Nothing fancy. Just connecting edges for strength. 10-15 is a good sized cat. Maybe double up on cardboard panels to win.

erin918 (author)2014-09-11

that adorable

EmeryGP (author)2014-09-09

That is so cute.

meismeems (author)2013-07-18

This is awesome, I never thought of doing the rafters when I cut up boxes for my kitties, that's brilliant! Mine are huge felines and they destroy boxes quickly with their playing, so the supports will keep it intact for a bit longer. Thanks!!

Nate230 (author)2013-06-10

This is an amazing makeshift cat tower and you are even able to add on unlike the $300 ones.

thing 2 (author)2009-08-08

That is very cool! nice!!! ;-) I wonder if like a guinea pig, lizard, puppy, ferret, weasel, or any other small animal would play in it! Can you give me any ideas of small pets that would play in it? I have two dogs so i don't think we'll get a cat :-( in some ways that's sad in others it's alright :-|

narex (author)thing 22009-08-08

you could get a rat and make this its would have to make it more secure though. I think you should get a ferret they are really playful so they would like it and they could defend themselves aganist a dog too, like a cat. I think a ferret castle would be awesome!

Rumbo (author)narex2011-12-29

I tried SO HARD to convince my parents to let me get rats, but i couldn't convince them enough. :(

komecake (author)narex2009-10-26

  The only problem with making a box system this large and complex for rats is that you will have to get rid of it in a week or two because yours rat will pee all over it. Lol.

aseaheru (author)narex2009-09-15

my famlys dog LOVES our 5, was once norm. 7, when one had 4 kittens..... cats. our 3 girbles are ingnored by cats....... old f. cat + teddy bear + sorange cat = f. cat attacking 2 others and others fight each other.......

thing 2 (author)narex2009-08-09

I'm probably not going to be able to get a rat. I wish sorrtuv. I like the idea of a ferret! Well if you think of more get back to me... Thanks Narex....

thing 2 (author)thing 22009-08-09

Oh yeah....... how much does your cat plat in it?

thing 2 (author)thing 22009-08-10

I meant how much does your cat play in it?

MatthewEnderle (author)thing 22011-12-29

Hedgehog... name it sonic... not the breakfast place. or Tiffany, that's a breakfast place too.

komecake (author)thing 22009-10-26

  I have pet rats and they LOVE boxes. They make great pets and are very smart so things like this are required to keep them entertained. 

 If you are thinking of getting a small pet I would recommend a rat. Keep in mind though that they are a lot of work and require a lot of attention compared to some small animals because of their intelligence. If you want a small pet that will respond and act like  puppy, get a rat or two... or three! :P

AznPanda (author)2010-04-02

Hey what kind of cat is this?
And awesome instructable i want to try to make this one day if i ever get a cat.

quesoman (author)2009-11-27

OK. I have only three things to say:
1. Your cat is extremely cute!
2. This is genius.
3. When I get a cat I already know that my cats castle will be near the foot of my bed and the balcony will lead out onto my bed.

Did I mention that this is genius?

grundisimo (author)2009-07-09

Awwwwwwww!!!! your cat is SOOOcute!!!!

Ideal_Ideas91 (author)2009-06-30

i built one of these about 3 years ago and my cat loved it! Animals seem to love Fleece blankets so i gave her my fluffiest one and she spent almost all of her time in it! It was big enough to fit 4 cats streched out and 6 if they laid nice and neatly. My parents didnt like it though and after about a year i had to rid of it

Foehammer358 (author)2009-05-01

thanks allot!! I'm building mine right now.... i might post pictures later.... you really make people want to make one... Gratz, its hard to do that. i only changed the design on three points, I'm adding a scratching post on the outside,I'm adding a hammock on the second floor(:D) and I'm putting piece of cloth for the door, to cover the opening. you don't care about that though, do ya? BEST INSTRUCTABLE EVER!

ve2vfd (author)2009-04-17

It's pretty cool! Now the big question... how does your kitten like it? :)

narex (author)ve2vfd2009-04-18

Yeah, if you put her in she'll sit in there for a bit but will come back later on and sleep in there which is pretty sweet! Some cats are just fussy eh?!

trypeewee (author)2009-04-17

NICE! I'll try it this weekend, if I can find the time. Did your cat liked it? Is it appropriate for him to sleep inside the castle?

narex (author)trypeewee2009-04-18

The cat likes it and it seems quite safe for her to sleep in.

marcward86 (author)2009-04-17

hahaha! this is wonderful. i'm glad you put so much work into a cardboard cat house.

lemonie (author)2009-04-17

I like the construction techniques, who needs glue eh? L

Cartermarquis (author)2009-04-17

Awesome. I would make something like this but my cats are probably too big, and one of my cat already chews out of the cardboard carrier we use to take him to the vet.
