Welcome to the Board Biskitt.
One of the most essential items in my mind is a crate, but make sure you get it big enough. When we first got one we got a medium size, luckily we got it from a small pet store that we always went to, we had to exchange it for a large size after a couple of months, as we could see that it wouldn't be big enough. You can always make it smaller by putting something inside, but never bigger!
