humane way to keep my cat from the top of my monitor?
First, lets get this out of the way …. Yes, I have an old monitor and not a flat screen. One of my cat, Nigel, sits on top of the monitor to look out the window. That would be fine, except that swings his tail in my opinion. I tried putting one of those silly hamsters mechanical dancing up there who is afraid of, but once it goes out, picks it up like a dead rat and escapes with him. What work? Spray bottles have no effect on this cat. Double stick tape maybe?
You could try compressed air. Works Great on my cat. Just do not spray to the face, the noise is usually sufficient.
