Am I wrong for cussing out my sister for giving my cat to my cousin
In April 2025 my family cat gave birth to four kittens, my mother (45) had already made the decision that we were not going to keep any of the kittens way before they were born, she planned to sell the kittens and give them to family members when they weren't depending on their mom. I instantly bonded with one of the kittens and me and my family decided this kitten could be 'mine' until she was given away, I named her Bub, (ignore the silly name I thought as we weren't keeping them I didn't need to put much thought into the name)
Anyways, after a couple months I became very attached to Bub and it seemed she became attached to me as well. After ALOT of convincing, my mum decided we could keep Bub and she would remain my cat and I would take her with me when I move out which is this month (April 2026).
Sadly a couple months after my mum decided we could keep her, my mum started to develop severe allergic reactions to cat fur. She told me we wouldn't be able to keep the cat. My mums friend (we will call her Haylee) said she would happily take care of bub until I moved out and then I could have her back. As I'm unemployed, 18 and on a full time college course I don't have any income, Haylee said she was more than happy to pay for food, litter and any other things Bub needed while she was caring for her.
In March 2026 Haylee messaged my mum saying she might not be able to have Bub at hers anymore as she wasn't getting along with her other cats. After she told my mum this I had then started trying to look for somewhere else for Bub to stay.
One evening my sister (26, who we will call Cassie) called me and told me that she had picked Bub up from Haylee and that she will have the cat at hers until I move out. She did ask if I could occasionally buy food and litter for her, but ii made it clear to her I am not in a great financial position and will find it very difficult to do so. She understood.
Me and Cassie are VERY close and have been since we were little, we are very similar and I have even lived at her house multiple times when I was having problems at home during my teens. Sadly my sisters daughter (my niece. 4 years old) Started to have allergic reactions to the cat and my sister informed me she wouldn't be able to have the cat at her house anymore and that I would need to find somewhere for her to go.
I contacted friends and other family members asking if anyone could have the cat at theirs until next month (when I move out) One of my friends from college said that she would most likely be able to have the cat at hers and she tried asking her mum but she said to wait until they are back from holiday to make that decision. I told my sister and my mum this.
The other day, while I was at a friends house I got a call from a private number, It was my cousin (19F who we will call Kayleigh) I am not in contact with Kayleigh as I believe she is a horrible person, she is an alcoholic, has serious drug problems and when my mother was fostering her a few years ago she would steal large amounts of cash from me and my mum for drugs and alcohol and did a lot of other terrible things such as sleeping with one of my ex girlfriends while me and her were together.
When she had called me she had stated that she 'has my cat' I asked her why and she said that Cassie had given Bub to her. I instantly hung up and messaged my family group chat to see if this was true. Cassie replied confirming that she did give Bub to Kayleigh and said she couldn't have the cat at hers any longer as it was affecting her daughters health. I was instantly filled with rage and called her out asking why she thinks she had any right to give MY cat to someone who is not trustworthy.
My sister then started saying she was the one paying for the cat and caring for the cat so it is 'her cat'. This made me so angry and I told her she can call Kayleigh and tell her to bring the cat back now. (During this time I messaged one of my old friends asking if she was still looking for a cat, as she was when we were friends, and she said yes. I then arranged with this friend that I will come drop the cat off at her house as soon as I have it back off Kayleigh.)
Cassie refused to message Kayleigh and said she is not my cat anymore and I need to stop having a go at her for caring about her daughters health. As this argument was happening on my family group chat my Mum and Dad got involved calling me selfish and rude for arguing with my sister 'over a cat'.
I am not angry at my sister for giving my cat away in general as I understand that her daughters health comes first but I wish she would have either asked me or spoke to me before giving my cat to such an un trust worthy person.
Also before anyone comments on how I would be able to care for the cat after I move out, I start working a week before I move out which means I would have the income to buy food, litter and to pay for vet bills.
I will admit I was quite rude to my sister and did tell her to fuck off and not speak to me, but I feel like that was pretty justified.
Sorry this story was very long, but AIW?
