Calico cats are three coloured cats, white being the predominant colour and the other two are like patches on the white colouring.
Tortoiseshell cats have small or no white markings, based on that and from what I can see in the picture of her, I think Cali would fall in the tortoiseshell category but... I don't think it would be wrong to say she's a calico, I'm not sure!
I read somewhere that calico cats are tortoiseshells cats, they just happen to have more white, perhaps someone with more knowledge could give you a more confident answer.
