Review: Stop looking this is the Pet Gate you Want. - I did extensive research on screen doggy doors. I had one for years it lasted until my screen gave out (note if you can, re-screen your sliding glass screen door (or even one of your windows for your kitties that need to come in and out ) with “pet screen” makes all the difference not only with the durability but installation and it will last for years and years and years! As with anything else, this product has evolved over the years and I am very secure in getting this review and I don’t give money trust me I don’t have time to do this but this is important because it’s pet related and it’s the most friendliest most trainable most durable was easiest to install just go on YouTube search for this and Will give you step-by-step’s oh and by the way I installed mine without removing my screen door! I love the fact that this product is not only adorable (usually I want “clean lines” as in do I need a dog print on my screen door? BUT this design gives enough plastic but yet enough screen area that they can see through push their snout/ nose against it and walk through without ripping it it’s a great design it has screws nuts and bolts that strongly secure the door from the outside and the inside you don’t need any glue and it has a magnet at the bottom and a locking mechanism. I chose (as per my pictures) to place mine at the far right against the frame of the sliding glass door because I have a 9 year old 23 pound miniature dachshund who can be a little sloppy getting through the door so I’m not going to have him “jump up into it” this is the perfect fit and I know so because I’ve had it installed for three weeks now and it’s fabulous I absolutely love it! Perfect time for summer because they want to go go out and then they tap on the glass to come in and then they tap on the glass to go out and then they tap on the glass to come and anyone with dogs understand what I’m talking about and also I have two wonderful cats that use the door as well it took them a little longer to figure it out a week or so with coaxing and treats there are training videos on YouTube as well. Let’s just say this is going to save my summer! Main points: replace what kind of screen you have in your sliding glass screen door with “pet screening” it’s very easy to install (do it yourself you don’t need to hire anybody: it’s screen, spline and the tool to put the spline in and of course scissors to cut the screen it’s definitely simple and ridiculously inexpensive! Quickly educate yourself on how to install it like I said YouTube. The doors comes in two sizes I’ll got the small one I have a 23 pound who runs in and out very easily as well as a 22 pound cat; as I said, read the dimensions and how to measure your pet from shoulder to paw before you order. The large one isn’t that much more expensive it installs the same way. I would recommend that large one for up to 20 inches from shoulder to paw. They crouch when they come in. I hope this helped anyone thinking about doing this because it will save your summer and make your pets so much happier!!!
Review: Works great easy to install - This works great for our cat and small dog. It was easy to install. Our screen isn’t the firmest but it is holding up well. If it was to get heavy use I would recommend a heavier duty screen.
