Why are pets not considered as important of a responsibility?

I was talking to my brother about my goals and stuff and he says I have no responsibility. I have two dogs and a cat currently, I’m giving up rights to my mom or brother of my large dog and in exchange get another cat instead. And I need to get insurance on them (it’s one of my goals). We were talking about me getting a car and making payments to build credit. He said that I’m avoiding it and that I need to put myself first but my pets also matter to me. Pets have always been important to me and until I have a kid, hell even if I do they would both matter equally to me. He said I’m setting myself up for failure yet I’m not trying to live above my means.
