My Panda Bear sits on the window sill and waits for some strange cat to walk by so she can roar like a lion - and I mean ROAR. The first time this happened it scared me and the rest of the cats to death - she acts like she wants to go right through the window to get at the strange cat. She's also my little window screen destroyer. Panda's constantly in the alert - I always know when something or someone strange is in the vicinity. Guess that comes with growing up as a street kitten.
