When you work from home, your cat can quickly decide that your desk, chair, or office doorway belongs to her. I found that a few small changes to those spaces made it easier for both of us to share my home office without constantly having to move her out of the way. Here are three simple tweaks that helped me keep my cat off my keyboard, out of the doorway, and out of my chair.
Give the Desk a Decoy Perch

When I work from home, my cat doesn't want my attention as much as she wants the square of warm, high-status territory I park my hands on for eight hours. You can tell because she doesn't settle near me on the chair. She aims for the exact rectangle where the keys are, then does that slow, satisfied loaf that says, great, meeting's canceled. The fix that finally stuck for me wasn't shooing or spraying anything. It was making a better claimable spot that lives in the same "command center" zone.
I put a low, firm perch right beside the keyboard, touching the desk, so it reads as part of the same platform. A folded bath towel works, but a small, flat cat bed works better because it has edges and it stays put when they knead. The important part is placement: If the perch is too far from the desk, your cat may be less interested in it. I found that keeping it close to my keyboard worked best. I also slid my monitor up on a simple riser so the perch didn't block my screen, because once she could sit there without blocking my screen, she started using it regularly.
For the first couple days I "paid rent" for the new spot. A few treats dropped onto the perch when I sat down, plus a quick chin scratch only when she was on that bed. After that, it turned into her office: she could watch the hallway, track the dog, and still be close enough to supervise my typing without turning my space bar into a pillow. The funniest tell it worked is that she started grooming there, which is her version of hanging a flag.
Give Your Cat a Better Spot Than the Doorway

There's a specific work-from-home shift that makes some cats act like tiny bouncers: the office doorway turns into a checkpoint. Mine started doing it the week I had back-to-back calls and stopped wandering the house. I'd step out to refill coffee and she'd be parked on the threshold, body sideways, eyes half-lidded, forcing me to do the awkward little shuffle around her. When the dog walked by, she'd sit taller and hold the line. I started treating the doorway as part of her preferred territory rather than assuming she was simply being stubborn.
What helped was giving her another place to settle instead of the doorway. I put a small rug runner just inside the room, off to the side of the door swing, and fed her there for a few days (even if it's only part of breakfast). I used food to make that new spot more appealing. Then I added a vertical option: a cat tree or window perch that has a clear view of the hallway. A higher perch gave her another place to watch what was happening in the hallway. Once she started choosing the perch instead of the doorway, getting in and out of the room became much easier.
Two tiny details mattered more than I expected. One, I kept the runner and feeding spot consistent, even on weekends, because keeping the setup consistent made it easier for her to learn where I wanted her to settle. Two, I stopped stepping over her when she did plant herself in the doorway. Instead of stepping over her, I paused, called her toward the runner, and tossed a piece of kibble onto it. If your dog is part of the tension, a baby gate can give the cat a visual win without giving her the whole doorway to police.
Stop Accidental Territory Lotteries During Breaks

My biggest work-from-home mistake with cat territory wasn't the desk. It was my breaks. I'd pop up to grab the mail or swap laundry, come back, and find she'd stretched across my chair like she'd won a contest I didn't know we were running. If I pulled the chair out from under her, she'd act offended. If I waited her out, I'd be late to my next call. Either way, she learned that my leaving created a lottery for the best seat in the room.
So I started treating short breaks like I'm leaving a campsite. Before I get up, I do three quick resets that are boring but weirdly effective: I push my chair fully in, I slide my keyboard back under the monitor, and I put a small throw (one she likes) on the decoy perch from the first tip. That last part is the key because it gives her a clear, legal place to land while I'm gone. When I come back, I sit down immediately, even if I'm just checking one email, so she has less opportunity to settle into the chair while I'm away. On days when she's extra spicy, I keep a wand toy nearby and do 30 seconds of fast play right before a longer break. It gives her a short outlet for play before I settle back into work.
If you have a dog in the house, you may need to account for the extra traffic around the office. The dog may follow you when you leave, which can add more movement around the doorway. Closing the office door can backfire because now the cat guards the outside. What worked in my house was leaving the door open but adding a predictable break spot in the office itself: a little puzzle feeder I only put down when I leave the room for more than a minute. The house still feels like a shared space, but the rules stop changing every time I stand up.
