AITA for taking away my family’s bunny without discussing with them first?

I (26F) am from China and just finished my master’s degree in the US. My family financially supported me through both degrees. My parents are doing pretty well financially, and we have more money and assets than what they spent on me. In 2021, during the pandemic, I went back to China for half a year, and we got the bunny then. It was my idea, and my mom quickly agreed, often referring to the bunny as my brother since she was feeding both of us. She knew I would stay in the US for at least a few more years before we got the bunny.

Before I graduated, my mom talked about my future plans, saying that if I couldn’t fully support myself 5 months after my degree, I’d have to return to China as she wouldn’t send me money after that. I agreed, and a month before graduating, I got an internship and now a job, so I no longer need her financial support.

However, my mom has been pushing hard for me to return to China by downplaying everything in the US—food, travel, people, job—telling me China is better. She’s a strong patriot, and we never had a good relationship growing up. I also don’t want to return to China. While my country is great, I don’t like the social and work environments. I don’t know anyone there, and after living in the US for almost a decade, I’d be facing a new environment without a job, friends, or resources. Here, I have everything.

A few months ago, after I said I wasn’t planning to move back, my mom lied about my dad having brain damage symptoms and refused to take him to the hospital. I had to make an appointment for him out of worry, only to find out she was lying. Recently, she told me she’d drop the bunny at a park’s bunny playground and let it live there. I strongly opposed it because the weather can reach 40C (104F) in summer and -20C (-4F) in winter. The bunny came from a breeder who raised them in sanitized conditions, and poor food or water could be deadly. The breeder agreed that it was a bad idea. When I told my mom, she complained they’d been caring for the bunny for 3 years and thought I would take over. Since I’m not moving back, she planned to get rid of it. I offered to visit annually, but she said she’d only keep the bunny if I moved back and settled in China in November.

I contacted the breeder, and we agreed he would care for the bunny until I decide what to do. I’ll be paying him for this. When I told my mom, she was shocked, calling me an asshole for taking away their last connection to me and insisting she never wanted to give up the bunny. I explained I was just removing the burden she mentioned, and she could still visit the bunny, but she refused. Now I feel like an ungrateful jerk, but her using the bunny as leverage to make me move back really hurt me. I’ve been crying for days. Am I the asshole?
