Sensory, motor and cognitive alterations in aged cats

Area of Science:

• Gerontology
• Animal Behavior
• Neuroscience

Background:

• Aging in domestic cats can lead to sensory, motor, and cognitive alterations.
• Understanding these changes is crucial for feline welfare and comparative studies of aging.

Purpose of the Study:

• To investigate age-dependent changes in sensory, motor, and cognitive functions in cats.
• To characterize behavioral alterations associated with feline aging.

Main Methods:

• Three age groups of cats (1-3, 5-9, and 11-16 years) were tested.
• Behavioral assessments included locomotor activity, fine motor coordination, auditory reactivity, and spatial reversal learning.

Main Results:

• Older cats (11-16 years) exhibited altered locomotor habituation and increased auditory reactivity.
• Fine motor coordination remained intact in aged cats.
• Cats aged 11-16 years showed enhanced spatial reversal learning, outperforming younger groups.

Conclusions:

• Feline aging is associated with a spectrum of behavioral changes, affecting habituation and sensory processing.
• Cognitive functions, such as spatial learning, may improve with age in cats.
• Observed behavioral changes may correlate with neurophysiological alterations in the caudate nucleus.
