keeping cat off coffee table
Since you aren't observing the coffee table 24/7, it's best to have a "remote" device that will deter her every single time she gets up on it. Sticky Paws or double-sided tape around the edges or places where she climbs up on it would discourage her. A product newly available in the US is "Sssscat" which makes a noise and blows a puff of air whenever they cross the electric eye is wonderful (of course, it will limit *your* use of the coffee table while she's being trained, but it doesn't usually take more than a few tries before they decide it is just not worth it!). Also great for counters, tables, etc. www.sssscat.com
I'm not a big fan of squirt bottles, loud noises, etc. simply because you cannot always be there, so the consequences tend to be inconsistent. What they learn, mostly, is not to do it while you're looking! (However, I do love my "canned air" to keep them off the computer while I'm working, since I don't care if they are on it at other times,).
I have noticed with my 2 youngest boys (now 2-1/2) that they just don't get the concept of "no" at all. It's almost as if they cannot comprehend that *anything* should be forbidden to them! They are very, very smart about most things. I call them my "Indigo cats" after the book about "Indigo Children" of a few years ago. Repetition makes no impression on them whatsoever, so I wonder if your kitten is also too smart for her own good!
