Dream About Birthday Party With Pets

I was at a birthday party of a girl I went to highschool with and my best friend was there too. In my dream that girl was really rich and as a surprise she booked all the favourite artists of the guests that came to play live music. Mine and my best friend's favourite artist came and we were really excited but the others didn't like it. We also brought all our pets and I had my elderly cat with me and we were in an appartment really high up and the pets we're going in and out of a window, then had to climb down a net to get to the ground. I didn't want my cat to do that cause she is really old and I was scared she was gonna fall down. I tried to befriend her with the other pets but they all just growled at her, some even fought with her which made me really sad
