some pet products

I was just wondering if anyone has seen or used these products before? I am trying to find a way to keep my babes from the tree we just put up and the tables. hot sauce in small bowls worked for two nights then it dried up! I think I will use tape but I wanted to see what else was out there. These look like the best products and wanted some opinions. What with trees going up real soon, we all could probably use something!

cat scram
not so sure about this one because it would go off every time we walked by.

paws off
is this like sticky paws? it doesnt say!

shoocat
looks good

The only one that I've heard of is Shoocat. I've seen it sold in a few stores in Ausralia, though not many. I haven't used it myself but have talked to people who have with mixed results.
