The PetSafe 280US Big Cat Flap 4-Way, White

(Originally known as the Staywell 280 "Big Cat" Flap) is a small/medium sized pet door designed for installation in plate glass, tempered glass (with the help of a glazier) or any solid or hollow core door. It would also be appropriate for installation in a Plexiglas or polycarbonate panel substituted for a piece of tempered glass.

A 'core cover' piece is included for installation in a hollow core door whether metal, wood or storm door design.

PetSafe suggests that this size is appropriate for small to very large cats and dogs to about 22 lbs. As always, we suggest you simulate the opening and test with your pets before ordering.

A 4-way locking mechanism is included.

Flap is rigid and clear. White frame only.

This PetSafe Cat Flap is identical to the discontinued Staywell 270 Slim Profile except the 270 had a frosted, colorless frame.

  • Works great. Need to replace every few years if used very often. Needs 2 people to install review by Arlo
    5 4 Works great. Need to replace every few years if used very often. Needs 2 people to install

    I have used these for 9 years. Fenced in yard but
    10 cats. Have 2 doors in the bottom portion
    of my storm door. The doors get used a lot. It works
    very well. But due to lots of use has to be
    replaced every so often. It's the door that gets old and
    can break down. But like I said the doors get used quite often
    You need two people to install. Directions could much much
    clearer. Thanks

  • Brrr!! review by Helene
    5 2 Brrr!!

    Whenever the wind blows, which is often in this area, the flap blows open. I installed it through the livingroom wall. The livingroom is very cold in the winter months. The unit is so large that my larger dogs can go thru it.

  • not great review by scutty
    5 1 not great

    The door we got looks great the only problem that I got with it is that it does not close all the time, it gets stuck .... I would not buy this door the second time ...

    ed. note - Pet doors like this one swing from little 'ears' at the top of the flap. In some cases, we've seen the molding process leave some excess material around these ears which interferes with the free swinging. It shouldn't be there, of course, but if it is a quick fix is to remove the flap and make sure those ears are perfectly round with no excess material from the molding process. A little lubricant like vaseline would help as well.

  • We have a problem review by fresno cat lady
    5 2 We have a problem

    We've bought this door before and all went well. This time, however, the door doesn't swing freely and, in spite of my husband's several attempts to correct the problem, it often stays open after one of the cats goes outside. It's not good when we've either had heat or air on and this door remains open. As I said, we've bought this door before, so apparently this time we got a lemon. He'll probably keep fussing with it and possibly have some luck. At present, I check it several times a day, as we have numerous cats who go in and out to their outdoor enclosure and I close the door if it's been left standing open.

    ed. note Customer should call our customer service (we can't identify customers from these reviews). As a point of information, all pet doors with rigid flaps will bind if the frame is not perfectly level at all corners. Over-tightening a screw at one corner can be enough to cause a problem.

  • Works great review by Bert
    5 5 Works great

    I installed it through a wall, instead of a door, so had to manufacture my own tunnel and buy some threaded rod.. Other than that, it was quick and easy.. 2 hours, after I had the extra supplies I needed, from marking the walls - to shoving the cats through..
