Reddit user Sorrynotsorry222 posted the story in the site’s r/weddingplanning subreddit on Friday after initially looking for advice on how to deal with her sister’s behavior.

The user claimed that she is a travel nurse and that her sister cat sits for her when she’s away. However, when she got into a dispute about the engagement party, the bride-to-be wouldn’t let her take the animal home.

In a long post, the user explained that the engagement party was becoming too large and elaborate and she had told her sister she didn’t feel up to the task of organizing it on her own, according to Fox 32.

“I was non confrontational and did my best to not offend, but I did tell her that I felt the party was becoming excessive and that I feel I cannot plan a large party of 60 people without any help or communication from her,” she wrote.

“She told me she was hurt (???) and then proceeds to tell me she can no longer cat sit for me…..I’m a travel nurse and she’s been watching my cat while I’m away,” she went on.

The bride-to-be was cat sitting at the time of the dispute, so her sister told her she would pick up the cat. It was then that the dispute between them escalated and the issue of catnapping arose.

“[S]he cussed me out and threatened to let my cat out while I’m still at work (he’s indoor only),” the Reddit user wrote. “She said I cannot come back to pick up the cat because I am no longer welcome in her home. She said if I come by at all she will hurt me.”

“I called her a bridezilla then contacted the police,” the post said.

“I will be having a sherrif [sic] accompany me tonight to pick up my cat safely as I now fear for his own safety,” she added. “I don’t even care about the engagement party anymore but as a nurse she is now a danger to others and I fear the safety of myself and my animal.”

The Reddit user later added an update to the post, explaining that the police had accompanied her to her sister’s home and retrieved the cat.

She wrote that the “police came and they were cat people! Blessing in disguise. It was so silly to explain the situation but they agreed she is unstable and very petty.”

“SO crazy and I thank everyone for your support it has been an emotional day to say the least and I am so grateful that my cat was not harmed despite her threats to let him loose,” the user said.
