PETOMG CAT WALL PLANNING GUIDE · 04
A second cat changes the route.
A wall that works for one cat can become a controlled passage for two. Plan choices—not forced encounters—through entry, travel, destinations and return.
Map the cats before the modules
THE DECISION THIS GUIDE SHOULD RESOLVE
“Can every cat enter, pause and leave without being forced through another cat?”
READ THE SOCIAL MAP
Shared space does not prove shared access.
Two cats may use the same wall at different times while one still controls a landing, passage or destination. Watch ordinary movement before changing the layout.
Look for waiting, turning away, staring, following, displacement and a cat abandoning the route when the other arrives. These observations show where choice disappears.
Wait
Does one cat stay below until the other leaves?
Block
Can a cat occupy a connector and control everything beyond it?
Displace
Does another cat’s approach cause a resting cat to move?
Chase
Can fast pursuit continue because there is only one direction?
Avoid
Has one cat stopped using a destination it previously chose?
THE FOUR BOTTLENECKS
Find where one cat can control the wall.
A route becomes fragile when access to something valuable depends on one narrow decision point. Audit the structure from both directions and from each cat’s perspective.
ONE ENTRY
Every journey starts through the same gate.
A cat waiting on that gate can delay access to the entire wall.
Change: connect a second familiar entry where the wall and cat profiles allow it.SINGLE SPINE
All destinations depend on one narrow connector.
More modules above the spine do not create more access choices.
Change: create another travel branch or a meaningful bypass.SHARED PRIZE
One lookout or hideaway carries all the value.
Competition can concentrate around the most preferred destination.
Change: separate comparable destination experiences across the route.DEAD END
Resting requires retreating through an approaching cat.
A high-value place can become difficult to leave even when it is easy to reach.
Change: preserve an exit, reversal buffer or alternative descent.THE CHOICE TEST
Give value more than one path.
This is a planning lens, not an exact spacing rule. The real wall, approach direction, cat profiles and installation constraints still determine which choices are practical.
More than one cat can approach the wall without converging immediately.
A pause point does not become the only bridge to everything above it.
Rest, lookout and hiding value are not concentrated in one controllable place.
A cat can leave without passing directly through a cat approaching from below.

BUILD ROUTE CHOICES
Use different module roles for different problems.
Small connections extend movement. Platforms create more meaningful pause and repositioning space. Destinations create value. In a multi-cat route, repeating one role does not replace the others.

BRANCH & CONNECT
CM04 · CM05 · CM07 · CM18
Use connectors to build alternative travel sections. A compact step is not automatically a waiting or turnaround place.
BUFFER & REPOSITION
CM06 · CM12 · CM26 · CM27
Compare platform roles where a cat needs to pause, let another pass, turn or choose a different direction.
DISTRIBUTE VALUE
REST · LOOKOUT · HIDEAWAY
Separate preferred experiences across the wall instead of asking every cat to compete for one destination.FROM LINEAR TO RESILIENT
Three structural changes do most of the work.
Add another decision before the conflict point.
Do not wait until the top of the route to create choice. A branch below the controlled connector allows a cat to continue without confrontation.
Separate value, not only physical modules.
Two small steps are not two resources. Compare whether both cats can access meaningful rest, observation or hiding experiences in different locations.
Design the exit with the same care as the climb.
Check what happens when one cat is resting and another approaches. A return option should not force a head-on meeting at the narrowest point.
CHECK YOUR ROUTE FOR BOTTLENECKS
Build the first revision brief.
Select every repeated pattern you observe. The result identifies structural priorities; it does not prescribe exact spacing or guarantee compatibility.
Select the repeated access patterns.
Your structural priorities will appear here.
MATCH THE HOUSEHOLD
The same drawing does not solve every relationship.
Keep choice even when sharing looks easy.
Cats that rest together can still want separate access at another time. Avoid turning current harmony into required proximity.
Protect the slower cat from the faster route.
Use distinct entries, buffers and destinations so speed does not determine who controls the wall.
Treat the wall as one part of the environment.
Separated resources throughout the home, behavior assessment and professional guidance may be needed in addition to route changes.
WHAT SHOULD CHANGE NEXT?
Choose the smallest change that restores real choice.
The wall has enough roles but one poor connection.
Reposition the branch, buffer or return logic after confirming the new installation points.
Compare CM roles →The route lacks a second access or separated destination.
Add the missing function rather than repeating whichever module is easiest to place.
Explore add-on units →The cats, furniture and wall constraints affect one another.
Send the full wall and mark where waiting, blocking or displacement happens.
Start a design request →WHAT TO SEND PETOMG
Show the conflict point—not only the empty wall.
1. Full-wall photo and measurements
2. Number, age and approximate size of each cat
3. A short video of normal route use
4. Marked waiting, blocking or displacement location
5. Furniture each cat already uses to enter or leave
WHY THESE RECOMMENDATIONS MATTER
Choice and separated access reduce forced encounters.
FelineVMA guidance for multi-cat homes emphasizes multiple, separated resources and recognizes that tension can appear through subtle blocking, staring, chasing and avoidance. PETOMG translates those environmental principles into route-planning questions; a wall layout cannot diagnose or treat intercat tension.
