Ping/Pong - two of Ling's brothers (who were adopted together cause of it) were named Ping and Pong. The sisters were Ying and Yang
Anyway - try feeding Pong on a flat paper plate and see if she still does it.
And the pulling of the mat..........for the longest time we had a towel under the feeding bowls/water bowl of Keno's with no problems. Now Charlie decides he doesn't like it there any more and will pull out the towel and spill the water all over the floor - then look at you!
So now the bowls are in a cookie sheet to keep any spills from getting on the floor. Can't even put a towel IN the cookie sheet without him pulling it out.
