OMG my cat LOVES tape. We can't use packing tape without giving her a loop to bite and play with. Anytime someone's peeling off something sticky, she comes running...she's strange.
But this is how we trained ours, similar to the results of others.
Use a vocal sound that is consistent. Use the same command every time. Whether that be "NO!", or we use "HEY!". We started with a water spritzer as well. Use the voice command, and if that doesn't work, use the water. After a bit, they will start to associate the two, and you can just use the vocal command.
