I kept a spray bottle with water in it & when they were small I would spray them when I caught them. Did that when they scratched my furniture with thier nails too. Now all I have to do is pick up the bottle & poof they skatter, but just the same they STILL sneek on my work. If my projects are small I cover them with my cutting mats, rulers & so on, otherwise I use a table cloth. :hunf:
