They are very different

We have a stuffed tiger doll, so today I started to move it like a kitten might move. Izzy didn't care one little bit. She reacted the same way she woudl react if I were moving my hand or a shirt around. Nate however freaked out and go very very scared of the doll, to the point that he would sneak slowly up and tentively reatch out a paw to swat at it and then thing better of it.

How very odd.
