One of the signs; while vacuuming or sweeping the floor, those bundles of pet hair are no longer thought of as dust bunnies. They are rolags. In the wild. (If I've been really very lax, they are batts.) But they don't reflect poorly on my housekeeping standards, no. They mean I'm not brushing the dog (dogs, cat, whatever) enough and I'm losing valuable spin-able fiber.
Scipio's fur, especially his undercoat, is far to short to spin. But, enough of it seems to get caught up in my knitting and spinning that I don't think he should feel left out. Plus, he often 'supervises' my spinning activity. Last night he kept insisting on helping control the amount of twist (well, he claims he was only trying to help) entering the yarn. I'm trying to find a new hobby for Scipio, and this morning I hit on this, a live camera feed from the kelp tank at the Birch Aquarium. It did catch his attention.
