Sense: noun/2
The main difference is register and age. 'Kitty' is an informal, affectionate term — you use it when speaking to a cat or about a pet you are fond of. 'Cat' is the neutral everyday word that works in all situations, from a children's story to a veterinary report. 'Kitten' refers specifically to a very young cat (under about one year old), while 'kitty' can be any age. 'Feline' is formal or scientific — a vet might talk about 'feline health,' but you would not call to your pet 'Here, feline!' For everyday conversation, use 'cat' or, when feeling warm toward the animal, 'kitty.' For example: 'I saw a stray cat in the park' (neutral) vs. 'A little kitty followed me home — can we keep her?' (affectionate).

Etymology
'Kitty' comes from the old word 'kit' (a young cat) with the '-y' ending that makes it sound smaller or more lovable. The money-pool meaning appeared in the 1800s, possibly from poker games where players put coins into a shared pot — as if feeding a 'kitty.' The two uses are now completely separate: one is about a group fund, the other about a pet.
