Aww, sweet Poptart! Glad to see there has been a little bit of improvement. Baby steps are still steps! I hope you'll keep us updated on all of your hedgies' progress. Sending much love to you guys.
Thaddeus sleeps balled up, unless he's on my chest then he spreads out. My first hedgie, Quillson, almost always slept all sprawled out. So adorable! =D
Yeah, I agree it'll probably get lighter as time goes on. My Theodore had an extremely dark mask as a baby, but when he passed away at 5 years old you would have never known he had one at all.
