You deserve to get paid wayyyy more.  I've heard several times from veterinaries that people try to guilt them into giving away treatments for free or cheap. "Don't you love animals?" Like, yeah, but the people working on the animals need to get paid, equipment costs money, the office costs money. It's not cheap. In my opinion if you can't afford to take care of your pet you shouldn't really have one. Poor fat animals. Did you ever see a pet from baby stage up to adult? Wondering how fast they got fattened up by despicable fatties.
