If you have a cat, the cat likely takes over the entire house. So if you plan to invite guests over, take some time to clear your tome for any guests who may not want to smell litter box or see cat toys scattered around the house.
First, clean the litter box thoroughly so the smell doesn’t overpower the room. Second, pick up after your cat and consider washing your cat’s blankets and the cat itself so everything smells nice. You may be used to the smell of your cat, but other people may not be and the prominent odor of a cat can turn people off right away. Then again if people don’t like a cat, why are you inviting them over in the first place?
