The quick answer
An unsecured gap can lead to falls, trapping or escape even when it appears too small.
What to check first
Check the complete frame, screen strength, opening mechanism and nearby climbing furniture.
Why the details matter
Timing, frequency, body language, appetite, mobility, grooming and litter habits can separate an ordinary preference from a meaningful change.
What to do now
Use a professionally secure cat-proof screen and inspect it regularly.
Make the change cat-friendly
Keep the routine predictable, preserve an easy exit and introduce only one safe adjustment at a time so you can see what helps.
When to contact a veterinarian
A fall, trapped body, breathing difficulty or escape near traffic needs urgent action.
What to record
Note when it began, how often it happens and what occurs immediately before and after. Photos or a short video can help show change over time.
The practical takeaway
Start here: Use a professionally secure cat-proof screen and inspect it regularly. Follow the warning guidance when the pattern is sudden, persistent or paired with illness signs.
