Kitty through the door

A cat hole in the wall? Easy enough. But first, paws to think about how to do it – safely. Postmedia Network KEVIN GOULD / KEVIN GOULD/STANDARD-FREEHOLDER

Last week we cut out a cat hole, or essentially a large mouse hole, at the base of the wall nearest the staircase to the basement. The purpose of this miniature archway was to allow the home’s two felines, Tigger and Coco, free access to their litter box.

Because it’s worth mentioning a second time, when creating a hole in an existing wall, we don’t simply “cut” out the drywall, but instead, we “surgically” remove it. The reason for caution relates to the consequences one could experience, conservatively estimated at, zero to 10 per cent, ductwork damage – 25 per cent, plumbing and related flood damage – 50 per cent, severing an electrical circuit – 10 per cent, and death – five per cent (which computation is based on your 50/50 chance of surviving the cutting of an electrical circuit) should you simply cut through a wall.

Surgically removing a section of drywall means you’re cutting to the depth of the drywall, then basically letting this portion of drywall fall into your hands, keeping this removed portion intact. Observing what’s behind this removed portion of drywall will lead you to either continue the task, or if you’re faced with a series of copper pipes or wiring, place the piece of drywall back in position, patch things up, and either move on to another section of wall, or take this project off the to-do list.

When cutting out a section of drywall, whether it be for a cat hole or any other small renovation project, locate the center of the nearest stud on either side of where the hole will be, then cut your drywall from the center to center of these wall studs.

The reason for this strategy is twofold. One, you’ll rarely get into trouble cutting down the center of a stud, and two, replacing the piece of drywall, or re-fitting it back into position, will be easier when you have these two anchoring studs to work with.

Last word on cutting drywall, put a new blade in the utility knife, then be sure to lightly score the surface, then progressively cut a little deeper with every passing. Again, we’re looking to eliminate any bloodshed, or loss of one’s typing finger, by digging too deeply into drywall, then tugging on the knife in an attempt to cut out a square patch in four passes.

Hold a level, square, or solid straight edge against the wall, then lightly draw your knife downwards. Once you’ve scored over the line three to four times, either put your non-cutting hand behind your back or keep this steadying hand a few feet away, then make that final cut. No one has ever lost a finger doing things this way.

Next, we frame the hole. In the case of our arched cat hole, we’ll be cutting pieces of 2”x2” lumber the depth of our 2×4 wall, about 3 ½ inches, then stacking them between the drywall, following the contour of the arch. Set a bead of glue in between each block, using drywall screws to help hold them in place if necessary. Next, line the 2”x2” blocks with a fiberglass mesh tape (as opposed to regular paper drywall tape) vertically and horizontally, overlapping the drywall by a couple of inches on the outside of the arch. Then, using a flexible plastic drywall corner bead (available in 10 ft. sections), cut it to the desired length (cuts easily with scissors), then fit it around the arched drywall contour. Use 5/16 staples to hold the flexible corner in position. The flexible drywall bead will ensure a nice contour line around the arched hole.

Now you’re ready to apply the drywall mud. Mud the wall surfaces first, let dry one day, then mud the jamb, or inside wall of the hole. Essentially, we’re creating a classic lath and plaster archway, only on a kitty scale. Similar to any drywall repair, subsequent muddings and sandings will have you going further and further out from the hole, as you attempt to make this kitty entrance as level to the wall, and as inconspicuous as possible.

Good building.
