Just as we talked previously about getting a puppy as a gift, you may have gotten a kitten as gift. Felines need just as much if not more to adjust to a new home as a canine. They can be much more particular than dogs. They need to have a safe environment where they know they have a soft bed, places to play, eat, drink and use the bathroom.
You may need to make a place for 2-3 litter boxes to see which area your kitten prefers. Some prefer a fresh water bowl daily. My cat likes an ice cube added daily to her water.
This is the best time to get your kitten used to you handling them, playing with them, and starting an oral hygiene routine. The older they are when you start trying to brush teeth or just clean them with a washcloth, the harder it will be.
