you will need food water and a litter box. Tip: use one more litter box for every cat (you dont have to). So if you dont want to keep putting water out you can just levae the tolite open. But you have to put food out evey time it is empty. You will need to give the cat love and carring. When you first get a cat you should introduce them one room at a time. If you hve another cat you should introduce them last and if they fight it is normal so dont worry.
