>>33642032Cats do have some severe health issues that can prop up at any point in their life and do them in. Cats also have that strong wild animal instinct to not show weakness if they're sick, in pain etc. because weak animals tend to get targeted by bigger predators. A sick cat can lash out, hide in dark, hard-to-reach places and ultimately drop dead without the owner ever realizing that the cat was sick in the first place. If your human-loving, chill cat suddenly starts hissing, swatting and fleeing from you, a vet visit should be higher in your priorities than trying to make amends.
