Does anybody have any ideas on how to stop my deaf 8 month old kitty from climbing my glass shelves and knocking off collector's glassware pieces and other valuable items? Since she's deaf, "no!" doesn't work. I've tried rewarding her for getting down (even if I have to force her) and I've tried confining her to her "playpen/multi level crate" when after repeatedly forcing her off the shelves (a dozen times in an hour and a half) and nothing works. Help!!!
