If you don't already have it, a collar and ID tag would be a good idea. If the cat is not used to wearing a collar, start now, about a month before the move. And keep it on for 2 or 3 months after the move. Just in case the cat finds an open door or window. If you are not moving too far, and the cat gets out, it may very well head for "home," the old one. So this gives you extra piece of mind. I bought a house and moved 2 miles from an apartment. I had 4 cats at the time, oldest was 8. I took over the food and water dishes, litter box, scratching post, put it in one bedroom which was going to have very little furniture moving into it, ahead of time. Moving day, I took the cats over FIRST, left them in their room with the door closed. The movers arrived at the apartment and could pack without worrying about any escapes. At the house, we set the things for that one bedroom aside (in the living room), set up all the rest of the place, then moved the cats to a different bedroom while the movers set the furniture in that one room. I didn't even bother moving litter box or anything for the 20 minutes. tWhen the movers left, and I opened the 2d bedroom door. The cats scooted back to "their" room, which became their "safe zone" over the next week. I let them explore at their own pace. One was out and about in an hour, the last one didn't leave that first room for two days! It helps that the stuff is all the same, the old smells and so forth. Your cat will enjoy the stairs and all those new places to explore!
