The best guess for her age was around 2 years.
She eats them as soon as they come out, when I’ve seen her, but she does a thing where she spins around and then gets them from the floor, not directly, if that makes sense.
The vet said her teeth were okay, but that she had slight extra growth on her back molars. She said it was nothing to worry about at this point (no spurs or anything), just to keep up with lots of hay. We’ve also been giving her willow which she loves now, and have reduced her pellets to less than 1/4 cup to encourage more hay eating, so I’m hoping the next time we see the vet her teeth are all good.
With the opening and closing her mouth, sometimes I think it’s just a weird communication behavior. Sometimes when I open & close my mouth she will do it back, and we can go like that back & forth for a bit. I know I sound crazy saying that, though!
ETA – our floor is laminate, which she can run on just fine, but it may impact the gymnastics required to get the cecals directly?
