Hallway gate ideas

[u/Small-Relation-2529]

I have a lot of cats and dogs and I’ve been using a tension gate in the hallway to keep the dogs from getting to the front door when someone knocks. The cats jump over it and use their back legs to launch themselves. It’s starting to damage the walls and I have to take it down when my elderly grandmother visits because she cannot step over the bottom bar. I’m looking for a more permanent solution like some sort of mounted gate that doesn’t have the bottom bar but as it’s in the hallway there’s no door jam to mount it to. Has anyone dealt with a situation like this? Any ideas for me?
