PetSafe Interior 2-Way Locking Cat Door - Up to 15 lb

PetSafe has changed this door - and not for the better. It's sad that PetSafe appears to have decided to save a few cents on each door by taking away the magnet and felt that USED TO BE INCLUDED in older copies of this same cat door. (And I've replaced this exact same flap often enough to see that everything about this flap has stayed the same - except the missing magnet and felt - so I'm not confusing two different products.) Those two features helped weatherproof the door and kept the door 'stuck' shut when a bit of wind blew - and the felt strip around the edge of the flap reduced the wind seeping through. It seems that Petsafe has changed their description of this flap and now label it as an 'Internal' cat door. I don't remember that is the way they used to advertise it. Maybe they had complaints about this flap not being quite up to snuff to work well as an exterior cat door flap - but I'm sad that they took away a couple of the better features of the door. And I've had to buy MANY of these doors over the years - because they wear out and need to be replaced. If you get the locking version of this door - the cats will knock the fragile locking clip off after a while, or it will simply break, and you'll probably find this door will eventually break on you in other ways: (the hinge knob breaks off, or the flap itself cracks, etc.) You certainly won't be happy with this 'new' interior version of their door - if you're using it on an exterior door. The slightest gust of wind NOW blows the door open. (the old door would still blow open - at times - but the wind had to be harder for this to happen) You will now have to pay more for a different model of cat door to get an 'exterior' cat door from PetSafe. It's sad that PetSafe took away two good features of this door to 'force' us to pay more for an exterior cat door. The old version was 'good enough' to suffice as an exterior door for some of us.

cons - too small. good for kittens.

It's exactly what I wanted and is a good size for my cats.

No magnet if I remember correctly. Kept flapping with wind

Pretty easy to put on. Adhesive could be a bit stronger. Lock doesn't work if your door is not level.
