You'll recall that a couple of months ago my boys discovered the wonders of the kitchen counter. It was a loss of innocence, both for them and for us.
Since then, we've cat-proofed the counter to make it boring for them and we've strategically positioned our Skat-Kat cat deterrant at various points on the counter. The boys have at least gotten the message that we disapprove of them going up on the counter so they mainly do it when we're not looking.
Every time I see Arthur or Beowulf in the kitchen sink, I hit them with a stream of cold water from the sink, but today I caught Beowulf hiding in the sink and the water did not deter him. When I finally picked him up and removed him from the sink, he came back to lick the faucet. I think I created a monster, a cat that likes water!
