When you first bring a kitty home, there will need to be a transition period for both the kitten and the members of your household. A kitten is tiny, and it’s curious about everything, so no matter where you are, at any time the kitten could be right behind you, in front of you, or trying to climb up your leg! In order to get through the transition period without becoming a bundle of nerves, the best thing you can do for the kitten and yourself is to create a safe zone. This is a place where you can put kitty so you know their safe and not going to get trod on, and where kitty also knows they’ll be safe from getting stood on!
Find a large cardboard box, approximately 3 feet square, plus at least 3 feet high. Organize the inside of the box so that there are specific areas for specific things, such as a sleeping corner, some paper to go potty on (if there’s room for a temporary litter tray in there all the better!), and a supply of fresh water that’s not easily knocked over. Also give the kitten a couple of small toys to play with so they don’t get bored. This becomes like a toddlers playpen. It’s somewhere you know they're safe.
As with a toddler however, their going to try and get out once the novelty of the box is gone and it’s been completely explored. They’ll take a jump over the top of the box, so make sure that you use a box that’s quite sturdy and won’t fall over if they manage to hang over the top of it – you also don’t want to make it so high that if they do manage to get over the top, and fall out, they're not going to hurt themselves – you could place a cushion at the base of the side most likely to be the “escape route” just in case. You also should place the box in a shady area, away from sunlight, and out of the way of drapes because if they can, they’ll make a jump for the drapes and escape that way!
Despite the escape possibility, the safe zone will give you peace of mind, especially in the early days when you’re still adjusting to having them around, and it will give them some place of their own to retreat too when they have had enough of the “big” world inside your home. Although they may want to escape the box, there will be other times when it all gets to be a bit much and they will actually sit beside their safe zone – or attempt to jump in it!
