How about sharing some of your favourite silly things about your companion animals, past or present?!
For example: My dog Jack has sudden bursts of energy where he has to run like mad for 30 seconds. Like this:
Hit wall, run 10 feet, hit other wall, run ten feet, etc.
Then he lies down and acts like nothing even happened.
Or how about my kitty DaVinci: He likes to grab ankles from under the couch/bed.
But he is very sneaky about it, he doesn't just run under the couch and go in for the kill. He will be sleeping for about 2 hours and I guess he says to himself "ahhh, that was a great sleep....OMGZ ANKELS!!!!!"
I'm sure your animals do more interesting things, so, um, share!
