My sister was totally offended when my mom went to a hotel

The only reason why she can stay here is because we have an air purifier in the spare bedroom.

My sister knows that my mom doesn’t like cats, but she still insisted that my mom would have a great time staying with her for 3 days. My mom asked my sister if the cats were going to be in the entire house and my sister told my mom that she would keep them in her bedroom. When my mom got to my sister’s apartment, all of the furniture and the carpets were covered in cat hair. My mom started sneezing immediately. My mom told my sister that she wasn’t going to be able to stay there and my sister went crazy. She was completely offended and suggested that my mom hates animals. My mom went to a hotel and my sister refused to answer her calls for 2 days. My sister didn’t talk to my mom until the night before she was supposed to leave to go back home. I know my sister loves her cats, but I think she was really taking it too far. My mom even complains about the animals in my house and I only have a small puppy. The only reason why she can stay here is because we have an air purifier in the spare bedroom. My sister should have put an air purifier in the house for a couple of days. I told my sister there was a place that would rent an indoor air purifier for a couple of days, so mom wouldn’t have such a terrible time breathing. My sister can’t get upset because my mom went to a hotel. If she can’t breathe, she can’t have fun on vacation.
