Re: Disciplining Cats
What's going to work also varies with the individual cat.
A firm, "No!" always worked for the cats we had growing up, but when I got my ladies they clearly had no idea what "No!" meant. They jumped on the table, I shouted, "No!" They looked at me happily. "The person is TALKING to me! Hello, person!" (Sometimes they would jump off the table to come say hello, because I was TALKING to them, but that wasn't really the effect I was going for.)
A can of pennies started them briefly (to the point of freezing, not to the point of jumping down.) Then once they realized it was just me making the noise, it had the same effect as "No!" "The person is making noises at me! Hello, person!"
Squirt bottles worked on Misty, but Stormy just sat where she was and glared at me. "Hey! You're making me WET!"
Eventually someone here suggested repeating, "Down! Down!" in a firm voice and shoving the offending cat unceremoniously off the table on the second or third "Down!" Cats hate it when they suddenly find themselves somewhere it wasn't their idea to be, and that eventually worked. At least, it worked to the extent that the realized I didn't want them on the table, and that "Down!" meant they should jump down. (They seem to have gotten, "No!" in the same tone of voice, either by extension or from repeated, "No!" followed by removal from the area they were committing the offense in.)
They still don't always jump down on the first "Down!" and sometimes a shove is still needed. And yeah, if they're in a stubborn mood, I generally eventually give up and just inform them I'm ignoring them. Then I do it. They have nothing better to do than to spend all evening jumping on the table, but I have other things I'd rather do than spend all evening shoving them off. (And at that point, I often suspect it's all an attention-grabbing ploy anyway.)
