Educational information, not veterinary advice or a home vision test. Do not darken a room, add obstacles or shine light into the eyes. If sight changes or you are worried, seek veterinary advice as soon as possible; do not wait for notes or an app reply.
Adaptation is not a test result
Cats Protection explains that cats with reduced sight can adapt and use other senses, including whiskers and scent information. That supports a modest conclusion: moving around familiar surroundings is not the same as having had eyesight checked.
Keep the layout record descriptive
An existing lamp, doorway, food bowl or recently moved chair can be recorded without asking the cat to negotiate it again. The note tool distinguishes what was present from what a person thinks the cat perceived. It contains no visual-acuity scale.
Do not create obstacles to answer a question
Cats Protection advises avoiding unexpected obstacles and moving familiar furniture when supporting a blind cat. This guide asks for no new barrier, changed route or demonstration. An unknown can remain unknown while you seek appropriate advice.
Professional care remains separate
A room note does not diagnose blindness or establish that a cat needs only a brighter bulb. If movement or sight has changed, contact the veterinary team as soon as possible. Support for a cat with an established condition should follow that team’s individual guidance.
