Yes, please do cut the thread into short lengths. I have zebra finches, and it's soooo easy for them to get thread wrapped around their tiny feet. I used to give them tiny fabric scraps for their nests, which they LOVED, but I stopped giving it to them the day one's toenail got hung up in the threads. Luckily it managed to free itself, but I was >thisclose< to having to capture it and untangle its foot. :shock:
