they do imprint. It's not a maternal instinct, it's recognition. It recognizes a certain smell to mean a certain thing. I may be wrong in thinking that's what imprinting is, though.
I don't consider love to be an emotion, however. Bonding is a social animal thing, though. So I suppose I am mistaking a preference to be a bond.
even still. its hard to say for sure, to be honest. no matter which side you look at, neither of us know for sure because we are simply going off logic and observations. It's only natural for us to attribute something familiar to ourselves to other people/animals.
And it's our instinct to do so.
