A four-way checklist of the situations around the marks you find
Enter the observation period and how many marks you found in it, then tick the items that apply across four groups: changes at home, other cats and outside triggers, litter box setup, and posture during urination. The result shows the total checked, the spread across groups, marks per day, the average gap between marks and the list of items you ticked. If you tick an item that suggests pain while urinating, a call-now line appears at the top of the result.
No validated screening table turns a checklist into a cause for spraying, so this tool names no cause and ranks nothing. The litter box items follow the placement principles in the AAHA and AAFP feline life stage guidelines: one more box than the number of cats, boxes kept apart rather than side by side, and at least one per floor. Reviewed as of October 2026.

Frequently Asked Questions
No. There is no validated screening table that turns a checklist into a cause, so this tool only shows how many items apply and which ones. Judging the cause belongs to your veterinarian.
Recording both postures separately gives the clinic a useful clue. Appearance alone cannot separate disease from marking, so this tool logs the posture without interpreting it.
The AAHA and AAFP feline life stage guidelines call for one more box than the number of cats, placed apart rather than side by side, with at least one per floor. Use a dedicated litter box tool for the count.
