My son has a dog which when the sound of the truck she drives arrives in, the dog practically falls apart trying to get out the door to meet her, for she brings him morsels of meat left overs from her job.
The dog does have dry cereal, less appetizing but yet eats because there's nothing else.
Given a preference, the dog, would prefer the morsels over the cereal, any time.
I'm not sure that that is considered a want, as in reasoning, but more a trained behavior based on taste and or smell.
My basing it on reasoning requires a choice, where their might be a need for a little salt or pepper.
I don't deny the animals from having a spirit from God, but not an intelligent spirit as ours, which I believe defines us from them.
