Rory's Feline Good

Building a cat submarine


OK, so I know that I might have a little bit too much time on my hands but I built a cat submarine for Rory and Mac!  I think that making it was definitely worth the effort though.  Rory and Mac are typical of cats in that they do not normally like anything that is actually meant for them (our collection of brand new, never been touched cat beds is testament to this).  However, they actually really love the submarine, although I admit that this is probably because it’s basically a box.

To make the submarine you will need:

  • One square cardboard box big enough for your cat
  • One small cardboard box
  • Extra cardboard to close the ends
  • Thin cardboard and toilet roll tubes for the decorations
  • A long steel ruler
  • A glue gun (other blue would probably work)
  • Stanley knife (and cutting board helps)
  • Pencil
  • Non-toxic paint and brush

1. Flatten out the square box and cut triangles away from each corner of the flaps.  I measured 8 cm in to make mine:

2. Cut a circle in one side of the box to be the “portal”.  It should be large enough for your cat to get in and out of:


3. Open the box and fold in the flaps at one end until they touch.  Glue the seams together and then do the other side:

4. Cut a hole in the top of the box, just smaller than the base of your small box.  Cut a hole in the bottom of the small box and a small portal in either side.  Then glue the small box to the top of the box.

5.  Using card cover the open ends of the square box and glue into place.


6.  Paint the whole thing – I went for yellow!

7.  While you wait for the paint to dry you can make your accessories.  Use your imagination here –  I made a periscope (out of a toilet role tube), a propeller, some fins and circles to go around the portholes.  Once dry to can glue these all on.


8. The finished product.  Once dry release the cats!

  4. Amazing idea—perhaps you have a nautical background. I saw someone with a Doctor Who cat TARDIS somewhere.
