Only animals from the classes of the Chordata phylum are included. [1] On average, captive animals (especially mammals) live longer than wild animals. This may be due to the fact that with proper treatment, captivity can provide refuge against diseases, competition with others of the same species and predators. Most notably, animals with ...
In old age dogs may develop dementia, which is associated with amyloid-beta, a misfolded protein that has been observed in both dogs and humans. [12] The most common effects of aging are: [23] Loss of hearing; Loss of vision ; Decreased activity, more sleeping, and reduced energy (in part due to reduced lung function)
Deafness in animals can occur as either unilateral (one ear affected) or bilateral (both ears affected). This occurrence of either type of deafness seems to be relatively the same in both mixed-breed animals and pure-breed animals. [5] Research has found a significant association between deafness in dogs and the pigment genes piebald and merle ...
Researchers have found a link between hearing loss and dementia. A recent study shows that people with hearing loss not using hearing aids had a 42% higher risk of all-cause dementia than people ...

Frontotemporal dementia is the most common form of dementia among adults under 60. After symptoms arise, the average life expectancy is seven to 13 years.
[2] [4] It has also been found that the greater a cat's weight, the lower its life expectancy on average. [4] The current oldest verified cat alive is Flossie, who was born in 1995 in England, United Kingdom. [10] A common misconception in cat aging (and dog aging) is that a cat ages the equivalent of what a human would age in seven years each ...
