Prepare Their Bathroom
If you’ve never had a cat before, you might assume you can simply buy a litter box, toss it in the basement and call it a day. This would be a mistake—although they are generally easy-going roomies, cats can be picky about their bathrooms.
“The most problems I see with new cats entering the home tend to revolve around toileting habits,” says Dr. Belinda Parsons, an Australia-based veterinarian. “The rule of thumb is one extra litter box [per] the number of cats in the house. And be aware of where you place it.”
Avoid any high-traffic or noisy areas of the home (if their designated bathroom isn’t peaceful, cats will find a more comfortable place to attend to business), Parsons says. Different cats will have different preferences when it comes to the details, but in general, you’ll want a nice, roomy litter box and unscented litter. And above all, keep it clean—as in very, very clean. Just as you wouldn’t want to use an unflushed toilet, your cat won’t take kindly to an unscooped box.
