My kitties do the funniest thing when there is a flying bug or moth in the house. They BOTH go on full alert like pointer kitties and do this funny cackling sound. In the picture, you can see their mouths open while do this odd sound - eyes both on the BUG which was a stinging beetle that hubby rescued us from!! My brave kitties!! Eliot is on the table at left and Emily is on the counter - both cackling away!
