As long as you're not into the mortgage money or eating beans while your furbaby wears designer, you're okay. When you first bring them home they need everything. And then you don't know exactly what you're gonna want to use or not...gosh what's a girl to do....LOL
I think I ran into the thousands, so in my book you're doing real good, seriously. Take a deep breath. Assess what you've got. Start sorting out what you think you are actually going to use and go from there.. you'll slow down eventually, at least that is what I'm still telling myself
