Another thing about tape is that a rat will FREAK OUT if any gets stuck to them. Crass found a loose piece of masking tape in my room a couple weeks ago and got it stuck to her fur. She was like anic: until I could grab her and take it off.
Yes, $50 lol It's about $20 for the Aspen and $25-$30 for shipping I buy my 33lbs of Harlan and Aspen, it comes to $100. It only last me months because I have one cage
My Pets Unlimited sells it for $30/bag but is PU, and it's chips. I like shredded.
