I think this is a bit of the problem. Putting pets first is a really bad idea. Put yourself first. You can't care for anyone if you aren't taken care of. Put your family next. Your family is more important than any animal. I put my friends next. Then come my animals. Now I am not saying that your new clothes should be more important than your animals health and wellness. What I am saying is that your health and wellness should come before your animals. Convince your mom then get the snake. Nothing good can come from trying to do things in reverse.
