How to use the Pet Eye Aging Sign Checklist
As a dog or cat ages the lens changes, so the eye can look cloudy even when there is no cataract. This checklist counts how many of the eye changes you observed at home currently apply, and uses the last eye exam date with the recheck interval your veterinarian gave you to work out the next exam date and the days left.
No official table grades cataract risk by age alone. This tool therefore builds no age-band risk grade and simply displays the age you entered, and because guidance such as the AAHA life stage recommendations asks for intervals to be set per animal, only the interval your veterinarian chose is applied. The next date is the last exam date plus the months entered, clamped to the final day of the month when that calendar day does not exist (as of October 2026).
Appearance alone cannot separate age-related lens change from a cataract, and eye changes can progress quickly when diabetes is present. Vision testing and deciding whether surgery is an option are not supported here. This tool is for reference only and does not replace veterinary care. Contact your veterinarian right away if you notice symptoms or suspect a problem.
Frequently Asked Questions
Appearance alone cannot tell. Age-related lens change can look much the same, so only an eye examination by a veterinarian can separate the two.
No. No official table grades cataract risk by age band, so none was built. The age you enter is only displayed back in the result.
There is no official interval table for every pet. It depends on the eye findings and conditions such as diabetes, so enter the number of months your own veterinarian gave you.
