My Solitare doesn't look normal unless she has something in her mouth. Usually her red ball.
She has mostly grown out of it but she used to bring in rocks from out side. The first 9 months I had her , I sunk my hand down her gullet to fish for a rock more times than I could count. If I caught her quick enough after picking it up , I could pry her jaws open and shake her head and make it fall out.
L0L I used to do the same to break bittin or nippin.
they are gutteral critters L0L
