A Few Notes

When you start to put your cat castle together, keep in mind that the boxes you use need to be large enough for your cat to fit comfortably. He should be able to stand up, turn around, lie down, and climb through to the next room.

Ensure that any holes you cut are big enough for your cat to get through without getting stuck, and the entire structure should be stable. Keep an eye on the castle, particularly if it’s made with cardboard since cats have a reputation for chewing and destroying cardboard boxes. Replace with fresh boxes when they become damaged.3 cat face divider

Conclusion

So, now you have the ideas and tools to create the perfect castle for your perfect cat. You can also consider donating a cat castle to a shelter for cats. You’re only limited by time and materials, but you can use your imagination and come up with anything you want. Painting or adding material to the outside is a fun way to dress it up a little but be sure to add some of your cat’s favorite toys and blankets to make it extra cozy and fun.

In the long run, all you need is a bunch of boxes, something to cut them with, and something to stick them together, and you’ve got yourself a castle for your kitty!
