Once in a while I leave my webcam on and facing oscar just to see what he does when I'm not home and in the 2 hour's I wasn't home he pooped, ate his salad, ran around like 10 times, fell asleep a bit, ate again, and ran around a few more times lol!
I have thought about doing this with our Toothless because he is new to us (on month this past week) and I never know if he is eating his greens or just what he does when we are at school and work. I was fortunate this past week to work from home a few days and I built a make-shift play yard for him and he ran around and licked everything, pooped and eventually fell a sleep so hard that he didn't wake up when I put him back in his viv. I may move him to the play yard more often when we are home so he has some zoo animals to watch.
