Project completed January 2012
Many years ago we purchased an inexpensive living room set.
Over the years, these couches suffered many indignities
including various bodily fluids from cats and children, food
stains, and the cats using the couches as scratching posts.
Gradually we discarded these disgusting pieces of furniture
as they developed the ability to resist attempts to clean
them, not to mention our inability to undo the damage that
cats and children can inflict. We did retain one last piece
to use solely as a scratching post for the cats so that they
would have an alternative to scratching the newer furniture.
Knowing that this last piece of "cat furniture" was reaching
the limits at which molecular cohesion can bind couch atoms,
I decided to expand upon my CAT-O-TRON design into something
that could take the couch's place when we got rid of it. The
prototype, which I built for my parent's cats, was to be
hexagonal and sturdier than the garbage cat furniture that
pet stores sell. The first step involved purchasing enough
4x4 posts to build at least two of these contraptions.
The biggest problem at first, besides keeping my
ever-present assistant Anya away from spinning blades, was
figuring a way to produce 30 degree angled cuts without the
use of a band saw. I built a jig to do the job but finding
that this method produced horrible results instead used a
table saw to start the cut and then complete the cut with a
The base of the MEGA is broad enough to resist tipping the
structure, which cats have been found to be able to do if
the center of gravity of the contraption is too high.
To connect all of the pieces, I fabricated steel joints and
attached them to the posts with 4.5-inch bolts. The idea was
to be able to completely disassemble the MEGA for easy
transportation and reassembly.
The next step was the risers. Two each of 2-foot, 3-foot,
and 4-foot lengths with one 5-foot center riser.
I fabricated all of the joints with 1/8 inch steel, which I
suspect was overkill several times over but I didn't want to
risk having any of the pieces break off and injure a cat.
With the risers in place,
all of the horizontal connectors are installed.
Using my previous
CAT-O-TRON design, I fabricated three beds that will be
mounted to the structure.
I found some neutral carpet and attached it to the beds.
It took about 650 feet of
3/8 inch sisal twine to wrap the risers and horizontal
connectors. Even so, there was still much that was still
