K, just get ready to pay for all it's medical expenses (shots, neuturing), toys, kitty litter shits and all the food. Also registering the pet with the government and all that. Expensive as shit, but yeah.
Also, get ready to pay, as in you're gonna be paying all that shit yourself. No one else will be paying them.
And getting a pet is like getting a kid. So yeah. Prepared to be the fucking mother to that cat. Yeah. Unless if you're prepared to raise a child for the next 14 years, don't get it.
