Will rabbits love their owners unconditionally?

No, rabbits have a certain way of showing they love you, if they nudge you and like you it means they love you but if your rabbit isn't playful and sits in the corner he/she might be annoyed and lonely mostly because you either, A. Left it alone too long, B. Not cleaned it out lately and C. not enough food/water. [Maybe give it treats like carrots brussel sprouts]

But if you take care of it and pet it every day and feed it and water it

I'm sure it will love you ! <3
