Sudden Irrational Behavior in a Geriatric Cat

Geriatirc cats may be easily confused.

An elderly or "geriatric" cat is considered to be more than 12 years old. Certain behavioral changes are not normal to the aging process and should be considered a sign that the cat needs to see a vet.

Causes

Physical causes of sudden irrational behavior in older cats include arthritis, hyperthyroidism, deafness, blindness, loss of the sense of smell, feline cognitive syndrome or dementia. The cat reacts with seemingly irrational fear, aggression or anxiety because it is not feeling well or is having trouble getting about.

Warning

Feline dementia can be treated if caught in the early stages, but it gets worse if left untreated. Symptoms include the inability to recognize objects or people, getting stuck in corners of the home, missing the litter pan and changes in usual behavior.

Normal Geriatric Behaviors

Elderly cats are not as playful or as eager to hunt as younger cats. They also may have problems grooming themselves. Although these are changes in behavior, they usually do not need veterinary attention.
