This is just what i was looking for (a very tall gate with no horizontal parts that cats could climb on; it seems well made and is working well to keep my own cats separate from my daughter's (who is visiting) but still allow them to see/interact with each other so that they will hopefully become more friendly over time.

my one concern is that this gate is very heavy. . . and I do wonder if it could possibly be made with lighter materials and still function as effectively?
