Do cats get Alzheimer's disease like people do? As your cat ages, you may begin to notice behavioral changes, which may raise these concerns. The reality is that senior cats can develop dementia, called cognitive dysfunction syndrome.

It is not uncommon for cats to begin showing signs of decreased cognitive function in their golden years. Many cats tend to exhibit particular signs, though they will be a little different for every cat. You know your cat best and will likely notice changes in...MORE his behavior due to memory loss, disorientation, or other things that can lead to confusion.

    Every cat has a certain level of "talkativeness." Some are always quiet and purring while others meow about everything. The change seen with senior dementia is one of increased or excessive vocalizations and not just a simple meow.

    It is important to remember other possible causes of new or odd vocalizations....MORE These include pain due to arthritis or injury or, in some cases, changes related to hyperthyroidism.

    The confusion that comes along with senior dementia may lead some cats to "forget" their years of proper litter box behavior. Cats are fastidious, especially about their toilet manners, so a cat who goes outside the box all of a sudden is a cause for concern.

    The problem with this behavior is that inappropriate urination or defecation can be symptoms of many diseases. This is one you should definitely not brush off as just a sign of senility. Schedule an appointment with the vet so they...MORE can rule out an infection or impaction (constipation) before doing anything else.

    Cats love to keep themselves clean and looking good. If your feline friend begins to neglect this essential task, it's a sign that something's not quite right.

It's common for senile cats to no longer care about keeping their coat in good condition. If the cat is overweight, that may contribute to the problem as well because it may be too difficult to reach...MORE everywhere.

    Cats are also naturally nocturnal, as many of us find out with the occasional 2 a.m. wake up meows. Yet, you might notice that your cat begins to appear more anxious at night in her later years.

    Okay, we get that cats sleep a lot! It's what they do and how they spend the majority of their days and nights. This behavior in older cats is going to depend a lot on your personal observations.

    If your cat is sleeping longer than normal, this change may be due to cognitive decline. For instance, he may not wake up for his scheduled dinner time or fail to greet you at the door after work, but is sound asleep in his favorite spot.

    Again, some of our feline friends can be a little temperamental at times. They will either put up with you or not and it will typically be on their terms, so this is another change in your cat's particular behavior. 

    You may begin to notice that your cat doesn't respond as you have come to expect. Not seeming to recognize family members (or other pets) or becoming stressed under "normal" conditions may indicate senior dementia as well.

    This type of behavior is also a product of...MORE pain, so care should be taken to rule out arthritis, injury, etc.

    Cats suffering from senile dementia may "forget" to eat. Like the litter box, this is another sign that you should see the vet about because it can be linked to a serious health issue. Additionally, cats that go without food for too long are susceptible to hepatic lipidosis.

    There are many steps you can take...MORE that can help your cat, including diet changes and nutritional supplements. Sticking to routines and ensuring he stays active and engaged can also do wonders for reducing confusion and maintaining brain function.
