ya know. i have noticed that my 2 bigger guys aren't as active as they used to be. until food is introduced that is. i'm probably wrong, but i compare them to puppies and dogs. as they get older, they tend to calm down a wee bit. notice, i said a wee bit....lol i think as they get older, they calm down a bit. and remember, Lrrr is still relatively young, right? still a playful puppy??LOL
