Is AUTHOR wrong in the post ? POST : Yesterday I got into a shouting match with my uncle when he and his kids were at my apartment to pick up computer parts.

For some background info, my uncle's family has a cat too and they basically treat it like an action figure. They got it declawed because it kept scratching the kids, and then took it back to get declawed again on its back legs since it had started kick scratching them. I've seen the kids literally pull it out from under the couch by its tail when they want to play with it because it hides from them whenever they come into the room. 

Because of this, I told them that if they visit my apartment they aren't allowed to interact with my cat in any way, and I made sure to put her in a carrier just in case. As soon as they get there the kids immediately run over and start shaking the carrier, and I got mad and told them to leave. My uncle argued with me until I was shouting and threatening to call the cops before he agreed to leave, and I told them they would have to pick up the computer parts from my parents because they aren't allowed in my apartment ever again.

After this both of my parents and my grandma left angry messages on my phone telling me that I needed to apologize to them for the way I acted, because that is no way to treat family. I don't want to because I think they were being cruel to my cat after I made them specifically agree not to and now everyone is on my case about "breaking up the family over a cat" since my uncle doesn't want to talk to my parents until they get me under control. Am I in the wrong here? I honestly feel justified but literally no one is taking my side so I am questioning whether I was too forceful.
