AITA for kicking my sister out of my house because she refuses to stop feeding my cat vegan food?

A Reddit user recounts a tense familial situation after their sister moved in temporarily post-breakup. The problem started when the sister began insisting on feeding Whiskers, the user’s cat, a completely vegan diet, despite cats needing meat to survive.

Following numerous cautions and discovering her secretly bringing in non-vegan items, the user on Reddit insisted that she either cease the behavior or move out, which resulted in her moving out. Now, the Redditor is second-guessing whether they went too far by placing their cat’s well-being above familial relationships. Review the original account below for an in-depth look.

‘ AITA for kicking my sister out of my house because she refuses to stop feeding my cat vegan food?’

Alright, listen up. I’m a 29-year-old male, and I own a gorgeous cat called Whiskers. He’s been my trusty companion for more than eight years; I adore him more than words can describe. My younger sister, a 25-year-old female, just moved in for a short period. She needed a place to stay while she searched for a new job and a place to live after a difficult separation. That’s fine; family supports family.

Here’s the issue: my sister now believes she possesses the ability to communicate with cats and has unilaterally chosen to switch Whiskers to a vegan diet, arguing that “it’s healthier for him and the environment.” To begin with, Whiskers is a carnivore through and through; everyone understands that cats require meat! I’ve informed her numerous times that it’s detrimental to his health, and he clearly only wants to consume the chicken-flavored snacks I purchase for him.

She just grins, accusing me of lacking an open mind. It escalated to the point where I found her secretly mixing vegan cat food into his dish when she thought I couldn’t see her. That’s when I snapped and gave her an ultimatum: either cease this madness or leave. She opted for the latter, and now she’s calling me cruel for ending the relationship over “a cat’s food.”

I am LIVID that she believes she has superior knowledge regarding my cat’s health. Seriously, she’s prepared to jeopardize his health to force her ridiculous way of life onto him! Am I the asshole for prioritizing my cat over my sister?

CarpeCyprinidae −  NTA. Cats are obligate carnivores and you did the right thing to protect your pet from malnutrition

Ratchet_gurl24 −  But you didn’t kick her out over a ‘cats diet’. She left voluntarily. She repeatedly disrespected your wishes regarding your cat, and accused you of being closed minded. You gave her 2 options. 1# respect your wishes, or 2# get out. She chose the latter, rather than admit to her wrongdoing and stop crossing your boundaries.

ogiddyhearto −  yo honestly ur cat comes first here. like what’s up with her thinking whiskers can go vegan? sounds like she needs a reality check. good for u for stickin up for ur boy. family is important but so is keepin your pet healthy.

Critical-Off-Garlic −  Just to clarify, I love my sister and have supported her during her tough times, but this isn’t just about a cat! It’s like she’s trying to impose her crazy beliefs on me! Am I really the villain here?

MerryMoose923 −  NTA. Vegan diets are not good for cats – they are detrimental to a cat’s health. You gave your sister a choice – follow your rules when it comes to your cat, or get out. She chose to leave, and is now playing the victim. There is no way you are the A H in this situation. And good on you for making sure Whiskers has the best care/life.

lightlysaltedclams −  F**king with anyone’s animal should be an immediate “leave my house”. You’re just protecting your cat.

SamuelVimesTrained −  She chose to leave.. You actually did not kick her out. But she chooses being a (pathetic) victim because she cannot continue endangering your cats wellbeing…she is an animal abuser.. No mercy!. NTA

garlicheesebread −  NTA, and she also needs to quit f**king with your cat’s food without your permission because it’s probably gonna f**k his stomach up.

abominablesnowlady −  Ordinarily I am staunchly on the side of people over animals. But in this case NTA! She is essentially poisoning this cat. This has resulted in cats dying!

First-Lengthiness-16 −  NTA but why on earth would you expect a vegan to act rationally? There are few places on this planet that a vegan won’t stick their noses into.. Don’t let it back in your house

Was the original poster right to prioritize their cat’s well-being by asking their sister to leave, or was that too extreme of a response to a familial difference of opinion? What would you do if someone close to you didn’t agree with how you care for your pet? Let us know what you think in the comments!
