Double-Oh likes chewing on my hair.... its so annoying. He did it a lot more when he was younger and has kind of grown out of it as he got older, but oftentimes I will wake up in the middle of the night to him chomping on my hair. He ONLY does it when I'm sleeping anymore... the sneaky little guy!! So when I wake up and chunks of my hair is stiff... I know he's been chewing on it
