For cats that are in the house, it can be inconvenient to get up throughout the day to let them out into the backyard where they can explore. Fortunately, cat doors are a convenient feature to install because they allow cats to come and go as they please. Cat doors are available in a variety of shapes and sizes to accommodate the size of the feline, as well as the home. If it’s your first time purchasing a cat door, it can be a challenge to know what to buy. We took the time to research the best cat doors in 2021 to determine which ones were the most useful for pets to use.
The PetSafe Wall Entry Pet Door with Telescoping Tunnel is constructed from durable PVC plastic, and we found that it was built with greater strength when compared to similar pet doors. Two replaceable flaps keep the weather out and insulate the home from heat or cold. We found that even when it rained hard, no water entered the building. In some cases when temperatures drop below 20 degrees, the vinyl flap has a tendency to get stuck and isn’t as flexible, but this is only in harsh weather conditions, when cats are less likely to head outdoors anyway.
The durability of this pet door can withstand UV exposure for increased energy efficiency as the cat goes in and out. It can even install into several types of walls without special tools required. It’s recommended for cats up to 40 pounds, which makes it suitable for most adult pets. The telescoping tunnel is one of the most impressive features of the door because it allows you to adjust it to fit walls of different widths. The gray plastic closing door feature keeps unwanted critters out of the home and offers additional protection from the elements.
Our team thinks that one of the best features of this interior cat door is how minimalist it is, without screw holes or cat door framing. Cats up to 20 pounds can pass through comfortably through the charming shaped opening. The sticky tape used to stick the wooden finishing pieces to the door does not offer a lot of adhesion, but we found this to be an easy fix by adding strong glue for good measure. This is a minor issue and still makes purchasing the cat door worth owning.
The full-size interior has a cute cat-shaped cut-out design that makes it an adorable feature. The wide opening is smooth and allows cats to pass between rooms with ease without becoming snagged. Available in semi-gloss white, or it can be painted if needed. We found that most cats were quick to use the door without any hesitation or confusion.
The PetSafe Plastic Pet Door with Soft Tinted Flap is available in four sizes to accommodate different breeds and ages of cats. A snap-on closing panel is included when you want to prevent the cat from using the door at certain times or keep cold or wet weather outside. The minimal and sleek design of the cat door helped it blend in with its surroundings. The flap is a solid color but could benefit by being clear, allowing cats to see what’s on the other side of the door, but this is a minor issue that doesn’t affect the overall quality of the cat door. It may just take a few days for cats to feel comfortable going in and out of it.
Allow your cat easy access in and out of the house with this durable pet door featuring a snap-on panel to keep weather out. Easily installed, this pet door can also be painted as needed. Our testers said the detailed cutting template and instructions to make the installation process easy and straightforward. We also found it to hold up well when multiple cats used the door throughout the day.
