Two strategically placed squirt bottles has not been enough to effectively provide deterrent coverage across the entire house. Today, I found the perfect solution at the local variety store - a handy 6 pick of small water pistols.
I may have just wasted $1.99!
I remember reading awhile back that Bengal cats actually like being in the water. Which was certainly true when we gave him a bath long ago. So, maybe I need to keep working on the deterrents.
