I love cats.  Not a cat lady but I have three!
Like most other animals cats have poorer vision but a better sense of smell than humans.
I wonder how much stronger their sense of smell is compared to other animals
Im not sure but they can see in almost complete darkness despite being almost completely color blind.
I had no idea they were color blind.  Crazy they can see so well in the dark.
Despite being solitary hunters they are social animals having many different vocalizations like hissing, purring, and meowing.
I know chattering is one type of sound they make when hunting or want to hunt
Yeah. They also have a very high breeding rate.
