1. Buy unscented litter for new kitten.
Kittens can have a very sensitive sense of smell. While you might enjoy the scent of your brand new litter, it could be too potent for your kitten. Be sure to buy unscented litter so that the kitten won't get sick while they are still trying to adjust to their new home.
2. Set up a safe place in the home.
Kittens like to explore, and they like to be around people, but they aren't exactly stable on their feet and they're not exactly conscious of dangers that may lurk in your home. You'll want to set up an area for them to explore in, a safe haven for when they want to run around on their own.
3. Get a scratching post for your kitten.
Scratching posts are a necessity when you have a kitten in your home, and if you get one right away then it will be easier for the kitten to adapt. You don't want your kitten to start scratching the carpet or furniture while they are still getting used to the new environment, so be sure that they have their own place that they can use whenever they feel like it.
4. Purr-chase toys.
Kittens love to play, but they aren't always aware of their surroundings. You'll want to get them a few toys that they can play with by themselves, and that won't be dangerous for them to be around either, like a string of yarn or something similar.
5. Clear out your cupboards and drawers.
A kitten may be small now, but they will grow quickly. Make sure all of the big spaces have been cleared out so that there isn't anything within their reach that could be dangerous down the road. If there are any smaller items in your home then you should move them or better yet keep them out of sight at all times.
6. Install safety locks on your cabinets.
You don't want your kitten getting into things that could be harmful to it or that they wouldn't normally have access to. Safety locks are temporary but they'll keep your pantry from becoming a snack bin until you can put in a better locking system.
7. Buy the essentials.
If you haven't already, be sure to get a new collar for your kitten so that it's wearing identification at all times, as well as a pet carrier so that you can bring them with you if you need to leave the home unsupervised. You may also want to look into purchasing toys and feeding bowls so that they can eat easily when they're hungry and play around when they're bored.
