Colorado State University researchers looked at records from past clients to determine risk factors and common complaints for feline cognitive disorder syndrome. Owners cited excessive inappropriate vocalization, most often at night. It’s possible, however, that timing was a factor in making this the most common complaint. When looking at risk factors, age was significant, which is also not surprising.
What was interesting is that cats who lived in rural areas tended to have a lower risk of cognitive disorders than suburban and urban cats. That finding could be due to many factors, including less pollution, more environmental enrichment, possibly being outdoors, and other signs. More study will need to be done, of course, but this study confirmed that cognitive disorder is mainly a problem for senior cats
