Not to hijack the thread but is a bit of aspen in their mouths reason to worry? She DID get a tiny piece stuck in her mouth, and she was fussing with it after eating, but she freaked out when I tried to remove it so I let her be.
Is her face going to swell up or some horrible infection start because of it? I thought surely it must happen a fair amount with all the aspen people have in their enclosures.
