✓ Movement can trigger play, but ambushing a cat leaving the box can create serious resource stress.
✓ Observe: Look for role reversal, loose bodies, hiding and later box avoidance.
✓ Try this: Move boxes away from ambush points and add separate routes and play outlets.
Movement can trigger play, but ambushing a cat leaving the box can create serious resource stress. The useful question is not only what the moment resembles, but whether it fits this cat’s normal pattern. Context, frequency, recovery and accompanying changes make the interpretation safer and more accurate.
Distinguish play from pressure
Look for loose bodies, pauses, role reversal and normal recovery. Concern rises when one cat waits outside, pursues every time, blocks return routes or the chased cat hides and stops re-engaging.
Redesign the exit
Move the box away from dead ends and provide more than one clear route. Use large open boxes in separate quiet locations so one cat cannot monitor every toileting area.
Redirect predictable energy
Give the pursuing cat individual interactive play away from litter areas and reward calm movement past the box. Do not punish chasing or carry cats together; both can increase arousal around toileting.
Check health and output
Track urine and stool for each cat when possible. House-soiling, pain, blood or constipation needs veterinary advice. Repeated attempts with little or no urine is an emergency, especially in male cats.

A frightening first meeting does not prove two cats can never coexist. Separate them completely, restore normal eating and resting, then rebuild from scent to sight and shared space only while both cats remain relaxed and able to disengage.
