Hi, we need to have mittens spayed soon as she is about 5 months now and in my area it seems the vets run about 200-300. I was doing some research and a local shelter has a list of low cost spay/neuter places. this would run me about 35-50, much lower. My husband has been out of work the last 5 months so money is not overflowing at the moment however we are not willing to compromise her health just to save a few bucks so we were wondering if this is a good option? would the likely have the ability to care for an emergency that would come up? what would you recommend and why is there such a difference in pricing?
