This comment is probably the most ridiculous I've seen in the last 24 hours. Nowhere does it say OP doesn't like the cats. OP is upset for several damn good reasons, and you are either very ditzy or an asshole for making OP the "villain" here. Since you apparently didn't pay attention, allow me to break things down for you so you don't make another off-the-wall guilt tripping assumption. One: OP was not ASKED if they could take care of the cats. Their grandparent decided that they were going to take care of the cats, regardless of any reasons they can't or don't want to do so. Meaning they either see OP as nothing except for a butler, or that they guilt tripped OP into accepting- both of which are unhealthy behaviors at the very least, and could even be considered emotional abuse. Two: OP had no idea that they were about to end up taking care of cats until minutes before they arrived. They had no time to cat-proof the apartment, make sure they had supplies to care for said cats, or make one time arrangements with the manager. Three: OP could have gotten kicked out of their housing over being forced to care for the cats. Four: Keeping the apartment "tidy" isn't going to do shit when someone reports hearing or seeing a cat in OP's apartment. Five: The grandparents not only should have found a professional boarding house for pet instead of forcing OP to do so for free- in fact, the Grandparents are likely to not pay for any damages caused. Six: If the cats aren't fixed, they are going to spray everywhere, and it's damn near impossible to get rid of the smell.

Can you read, or are you just deliberately dense? The apartment doesn't allow animals. If they're strict about it, OP could be fined or even evicted if their landlord finds out.

Blood is thicker than water is incomplete. The correct phrase is "blood of the covenant is thicker than water of the womb." Which means the bonds we form are stronger than family.

That is not the correct phrase. The original "blood is thicker than water" appeared almost a 1000 years ago. Your version is a fraud from the past 20 years or so.

That phrase is total bullsh!t when all your family does is treat you like crap. Just because someone is blood related to you doesn't mean you owe them anything. If OPs grandparents respected him at all they would have asked first. They just assumed he'd do it because he is their grandson.

He probably said he'd do it and didn't know about the policy
