Dogs can learn up to 165 words or so (including gestures), and a few “super dogs” can learn around 200 words, similar to the human equivalent at around 2 years.
my dogs know sit, stay, down, paw, cookie, food, out, their names, cage, and shut up.
my cat knows his name.
my cat’s a moron.
you cat knows the entire English language but you are far below his level of intelligence so he just ignores you most of the time
