Need Ideas to Attach Pet Gate to Window

I'd cut a 12' or so length of 1 x 3 and attach one side of the gate to it. I'd attach that to the window frame or wall.

The other side I'd secure with a hook and eye or similar.

It might be a little less high when it's been expanded.

When you open and close the gate, the distance between the two "horizonatal" arms will change.

Why is it many of today's recent adults can't solve simple problems? One would think he would have had a plan before he bought the gate.

It's meant for a car. He or someone must have bought it for a car and not used it for that.

I'd probably make a frame that's a bit smaller than the closed gate. Fasten that securely. Put the gate on the inner side of the frame. That would at least keep the cat from pushing it open by brute force.

I'd like to thank everyone for their installation recommendations. I didn't mention that my window is frameless so I'm going with this recommendation because it can be implemented on the outside of the window drywall (with anchors).

I only need a 10"-12" board of 1/4" thickness to attach the gate securely to the outside of the window. My only reservation is that I'd need to drill a hole in each end of the left side of the plastic gate and I can only hope that the plastic won't shatter from a drilling. A hook for the other end would be perfect for allowing me to open the gate at will. Thanks again.

True, but there still won't be enough room for the cat to stick it's head through the top or bottom opening.

True. Perhaps I can get by with securing only one of the horizontal arms?

I just tried expanding the gate. You're correct. Each arm pivots a bit when stretched.

The initial plan I tried didn't work. Do you have a workable recommendation?

Yes. Throw that cheap piece of crap away and start over.
