It really just depends. Sometimes they are low-cost because they are not necessarily taking all the precautions that your regular vet may take. Sometimes those costs are higher because they include pre-anesthetic bloodwork, IV catheters and fluids, monitoring equipment, better pain medications, etc. Where I work, those things are standard and included in the price. Not having those things in place allows them to keep costs down, and people may elect to opt out of them (although I don't understand someone who would decline pain medication for their pet after a surgery like that!). I'm not saying your pet won't do fine, because the majority of pets being spayed/neutered are young and healthy, but I would take that into account. Some places do a better job than others, but sometimes, low cost comes from having high volume. You might want to ask about what steps do they take to ensure your pets safety, what they offer for pain control, and what you can do in case there is some kind of complication afterwards. I do know that they are offering a valuable service and there is a huge need for it. I would rather see a pet get spayed/neutered than not. It's just that I've seen some still operate at an acceptable level, and some really cut corners - jeopardizing your pet's health and well-being in the process. But lots of people use them and they are popular because sometimes that's what they can afford. Maybe another option would be to go to another vet hospital, but one whose costs are less, without compromising safety. Or see if your vet accepts vouchers, like a SNAP certificate, that will allow you to still have it done there.
