So I did end up grabbing one of those window perch seats and I swear it’s the flimsiest piece of crap ever but for the time being it can hold the whole 3.5 lbs of Snowflake right now. It literally is held onto the window sill with just a strip of velco. There are some legs that lean on the wall but I swear it will keel over one day. For now she enjoys her sights of the neighborhood and the things that go on around the place. There is even a tree in front of the window so she can birdy watch. The padding is pretty thick though which I was surprised about.
