My Mini Lop often only shows interest in toys given to her after she has come to realize, & acknowledge, that, yes, I really am just giving her the toy- and there are no sweet, tasty treats headed her way along with it.
In this case, however, she showed immediate interest in the wooden apple toy. She grabbed it and chewed it a bit as soon as I gave it to her. Shortly after that, she began excitedly tossing the toy around her playpen.
Not sure what the secret is with this toy- but it got my rabbit's approval!
