I always have this headcannon about Axel, he loves animals and they love him. If he goes to someones house and they have a cat it will just go to him instead of anyone else. Also he has wild animal that visit him at his house and he can wake upto deer and wolves, and even eagles in his house, either on his bed or waiting for him to bring some food out for them and sit with them while they eat. 

I always have an image of him cooking something to eat and having a wild animal trying to steal it from him and him lighly scolding them.
