Give your feline friend a way to easily get in and out of your home so they can go as they please. Whether you’re away for a period of time, or just need a convenient and easy way for your cat to travel freely throughout your home, PetSmart’s selection of cat doors is the perfect way for your kitty to roam freely. We carry cat doors in different sizes and varieties so both you and your cat will be sure to love your new pet door or flap.
If you're concerned about wildlife entering your home, try an electromagnetic cat door – which only functions when it senses a corresponding magnet. This way, your cat can come and go, but wild animals cannot. Keep in mind, a licensed contractor may be needed to properly install a cat door. 
Looking for other ways to keep your cat or kitten secure? PetSmart also carries a variety of containment solutions, like cat carriers and pens
Running low on other cat supplies? PetSmart has everything you need for your cat, like cleaning supplies and cat repellentscat food and treatslitter, and more. Take a trip down the cat aisles at your nearest PetSmart store or shop online for all your kitty’s favourites.
PetSmart also offers convenient shopping with curbside or in-store pickup. Need something today? We have select items available for same-day delivery in most areas powered by DoorDash. For items you purchase frequently, PetSmart has Autoship that automatically delivers the items you want to your door as often as you’d like. Check the website to see which items are eligible.
