This wiki has been updated 18 times since it was first published in October of 2018. If you're tired of having to constantly let your animals in and out when nature calls, these pet doors will allow them to come and go at their leisure. They install directly into your existing sliding glass doors, but be aware that any model that works on vinyl doors won't work on aluminum ones, so be sure to check the details thoroughly before you decide which one to purchase. When users buy our independently chosen editorial picks, we may earn commissions to help fund the Wiki.

Editor's Notes

October 08, 2020:

We've considered durability, ease of use, and affordability when making our selections, but not worried too much about "inaccurate" pet sizing. Most companies that make pet doors encourage you to measure your animal, anyway, and not just rely on weight ranges or size designations like "small" or "large." As with, for instance, clothing sizes, these can vary quite a bit, but a measuring tape, wielded properly, won't lie.

As for top choices, the PetSafe Freedom is still a reliable option, as is the PetSafe 2-Piece. The Freedom model is a single-piece unit, whereas the 2-Piece, as you can guess from the name, breaks down into two parts. This makes it easier to store than the former, but it doesn't come in as many size options as the Freedom. Options from Ideal remain popular, as well, including the Ideal Pet Products VIP and the Ideal Pet Products Fast Fit.

If you're in the market for something a bit fancier, take a look at the Thermo Panel 2e SureFlap, which gives you the well-liked SureFlap pet door in a frame that's designed for sliding glass doors. You can set it to recognize up to 32 pets, but they must be on the small side, as this model doesn't come in a large version.

October 23, 2018:

Weighed energy efficiency against ease-of-use when ranking the PetSafe Freedom over the Ideal Pet Products Fast Fit, ultimately deciding that a brief period of extra training would be more than offset by savings on utility bill. Investigated user reports to determine safety of the High Tech Pet Shorty and found no safety issues to note.

Special Honors

Pet Door Guys In The Glass Although it requires installation by a professional glazier, if you need a permanent, custom option, the Pet Door Guys In The Glass might be just the ticket. You'll have options when it comes to the flap size, step-over height, glass type, and more, with no weather stripping required.
