I went through a rough break up and moved to a new house. I came and cleaned and took all of my stuff out before the lease was up.

I tried reaching out a few times but got radio silence, so I stopped and started to try and focus on myself and move on.

A little over a month after moving out and paying the prorated amount of rent for the last month, I get a message saying the carpet needs to be replaced due to pee smell.

We all had pets. I had a cat, one of the house mates had a old cat and a dog, the other housemate has two cats that never left his room.

My cat, like most cats, was litter box trained. The old cat had some medical issues where he would throw up at least twice a week, and the dog was a puppy and was never properly potty trained. She would poop and pee on the carpet almost daily all over the house.

The bill came for replacing the entire house's carpet. About $460 each between 4 people.

The roommate, whose cats were in his room only, brought up the unfairness of him having to pay when the dog wasn't potty trained the entire time we lived there. I agreed and pointed out that my cat literally only used the litter box.

The other roommates cited that the bill was in all of our names so we all should pay it. One of them says they had to clean up my cats pee once and "who knows how many times he's done it".

We had my cat for two years and I've never been told he's peed anywhere but his litter box until now when a bill comes up. I've never seen him use anything but his litter box the entire time I had him.

We all know for a fact that the dog wasn't potty trained and all of us had took turns cleaning it up around the house.

They mentioned hiring a cleaning service when we all moved out, which I didn't know about because again, radio silence. Had I known that was something they wanted to do, I would have gladly offered to help out with the cost but I guess they wanted nothing to do with me, which is understandable.

I don't want to pay for something I had no part in. They said something about "not taking responsibility" when I brought it up.

AITAH for not wanting to pay the bill? The last thing I want to do is cause issue but I also don't want to be walked on. Part of me wants to take the path of least resistance but I don't think it's fair. I was fully ready to cut ties and move on but now it seems like they're making me seem guilty when it's clear their pets were causing the issue.

Update: thank you for your comments. I've decided to agree to pay it and be done with the whole situation. I was going to use my bonus this week to give myself a nice birthday, as it will be my first birthday alone. But now I'll put it to this bill and wipe my hands clean of this mess. I guess I'll spend the day at a bar or something. I'm also thinking about changing my number to completely cut contact from them. Glad to hear most people don't consider me an AH for feeling how I feel.
