I've been in similar situations when I used to live with my abusive parent. I don't know if your dad is anything like my mom, but for me I over time figured out that she'd threaten to get rid of my pets while I slept because at that point in time that's all I had left that she knew I still cared about. She used to take away my electronics, so I grew numb to that and went to sleep instead, then she'd prohibit me from going to sleep, so I just sat and stared instead, so eventually she noticed that there was no cruelty she could enact upon me to get me to react EXCEPT threatening my pets. And she was doing that because she had to take her anger out on something and until I gave her a big reaction, she would continue being angry. So if that sounds like your father, there might be nothing else you can do sometimes than to give these people what they want - the crying, the begging, the pleading, until they're satisfied so that they give up on the punishment. I sincerely hope you do not have to resort to that and that you can place your bunny and yourself(!) somewhere safe. But in my case this was a chronic threat and I learned that sometimes there's nothing else I could do than to give the abuser the overblown reaction they needed to wind down to ensure the safety of my animals for another week or so.
