Scientific proof that bears are not a type of animal

At supper table, talking about how I have to go to work and she has to go to daycare tomorrow...
(before daycare provider's husband called to tell me she would be closed due to illness....Bah!)

BSG: But you love me so much, you might cry a little at work!
Me: Yea, I might. Do you think you'll cry at [daycare] tomorrow?
BSG: No, I'll see myself.

While eating her carrots during lunch...

Me: Eating your vegetables will make you grow big and strong.
BSG: Yea, strong like a hippo.
pause...
BSG: or maybe like a rhinocerus!
Me: Which do you think is stronger, a hippo or a rhino?
some deep thinking by BSG...
BSG: A rhinoceros, because they have horns.

While reading the book "Never talk to Strangers", where all of the 'strangers' are different kinds of animals. We were on the page with a bear knocking at the door...

BSG: But a bear isn't a stranger because he's not an animal.
Me: Yes he is. A bear is a type of animal.
BSG: No it's not.
Me: Yes it is.
BSG: No it's not.
Me: What is a bear if he's not an animal?
BSG: It's a type of monster because it has scary teeth. See? (points to book, then touches bear's teeth in the picture). Ouch! Those teeth are sharp!
