As cats get older, some develop feline cognitive dysfunction, a brain-aging problem that can look like dementia. The signs can be real, but they can also be caused by other treatable medical issues, so behavior changes in a senior cat should not be written off as “just old age.”
Common signs include: disorientation in familiar places, staring or seeming “lost,” changes in sleep and wakefulness, increased night vocalizing, house soiling, anxiety, changes in interaction, reduced grooming, and sometimes changes in appetite. The pattern matters more than any single symptom.

What can look like cognitive decline
Several common senior-cat problems can mimic cognitive decline, including thyroid disease, kidney disease, high blood pressure, pain, and vision or hearing loss. Some cats also have more than one issue at the same time. That is one reason a proper veterinary exam matters.
In other words, a cat that is vocalizing at night, missing the litter box, or acting confused may have cognitive dysfunction, but that same cat could also have a medical condition that needs treatment.
What the vet will usually check
Veterinarians typically start with a detailed history, physical exam, and neurologic exam, then use tests to rule out common causes of behavior changes in older cats. That often includes bloodwork, urinalysis, and blood pressure measurement, with thyroid testing and other diagnostics as needed.
The goal is not just to label the behavior. It is to find treatable causes, identify pain or sensory loss, and decide whether the problem is likely cognitive decline, another disease, or both.
How to help at home
- Keep the routine predictable. Feed, play, and clean the litter box at consistent times.
- Make resources easy to reach. Use low-sided litter boxes, keep them in quiet places, and avoid forcing the cat to climb stairs for food, water, or the box if mobility is limited.
- Use night lights if your cat seems more confused in the dark.
- Keep furniture and important items in the same places when possible.
- Offer gentle enrichment, such as short play sessions, food puzzles that are easy to use, and calm social time.
- Track appetite, water intake, weight, and litter box habits so changes are easier to spot early.
If your cat has accidents, do not punish them. Accidents are a symptom, not disobedience.
When urgent care is needed
Call a veterinarian or emergency clinic right away if your cat has trouble breathing, collapses, has seizures, cannot urinate, seems suddenly blind, has severe weakness, cannot stand, has repeated vomiting or diarrhea, or refuses food for about 24 hours. A sudden major change in behavior or alertness is also urgent, especially in an older cat.
Outlook
There is no cure for cognitive dysfunction, but many cats do better with early diagnosis, treatment of underlying conditions, and practical home support. Some cats stay comfortable for a long time once pain, thyroid disease, blood pressure, or other contributing problems are addressed.
If the cat is no longer comfortable, eating, moving, or interacting in a meaningful way, talk with your veterinarian about quality-of-life planning and palliative care. The right next step is usually medical guidance, not guesswork.
