Depends on how sophisticated it is. My iPhone has been able to correctly identify and tell apart different cats for about 3 years now and gets it right 90% of the time.
And before I get the comments: yes, I’m about to fully leave the Apple ecosystem.
My current cats are pretty different: 1 tux and 1 brown tabby. However in the past we’ve had another 2 tuxes. Those are usually where the mixups happen, between the 3 tux cats. But even those tend to work out most of the time.
