It varies on the kitten. Kittens need things like cat food, litter boxes, kitten shampoo, toys and scratching posts. There are some supplies that will help your little one get through his or her early years easier such as an anti-bacterial toy box liner (which can be purchased at any pet store) or a bed for them to sleep in. Or you could make your own by cutting up old towels into squares and placing them onto cardboard; this way it’s easy to wipe down dirt and debris. You also might want to purchase some kind of kitty condo for them where they can climb all over it while you go about your day without having too much trouble cleaning up their messes!
