I do hope you will not bring him home till about 10-12 weeks minimum. They need to stay with mom and siblings for that long to be mentally and physically healthy. Also just for your info its NOT tuxedo. Its black/white bicolor (or blue/white bicolor) for your choices
Here's a basic list of supplies:
Litter, litter pan, scoop
Cat carrier (go for medium size or else you will be buying a new one by the time the cat is 8 months old)
Nail clippers, combs for grooming
Cat toys (balls, furry mice, feather toys)
Cat shampoo (keep some on hand in case you need it)
Cat bed (optional) - most will ignore it, but nice to have
Good sturdy treehouse (minimum of 4 feet high) - higher the better. Its a good investment. The smaller ones are a waste of money as most cats will not use it once they are adults cause it tips over.
As far as food - ideal is dry and canned food diet in quality foods. You can try:
Wellness, Natural Balance, Innva, Blue Buffalo, Royal Canin, Max Cat foods (in dry and canned). Be sure to start at on kitten foods. I only feed kitten food for about 4-5 months, then change to adult foods. Never had a fat cat doing this.
Also be sure your new kitten is spayed/neutered by 3-4 months old. Kittens as young as 4 months can and do breed and will get pregnant - they don't have to show signs of being in heat to breed.
And they still expect you to love them afterward.
