cats hate water. People say they use water guns to scare cats away or to get them to stop doing something. Try using a garden hose with a high pressure head.

good luck with the cat. did ya try calling any pet stores or vets or something and see if they have any other suggestions?

animals mark their territory. you're an animal too. go on. you know you want to. wink

shove lots of toothpicks in the soil around the plant, wont hurt the plant but will discourage the cat.
