Spay questions

I found a clinic that spays for $85 but I want to make sure that nothing bad (for the rabbit) is hidden behind the low cost. Last time I neutered my male for only 35 USD, I had a feeling that pain control wasn't adequate so I don't want to miss on this when spaying my female.
What questions should I ask the vet and what anesthesia is common and necessary for the spay surgery? I need to make sure they do it properly.

This is what I always ask the vet:

-What is your success rate?
-How many times have you sprayed or neutered a rabbit?
-How many deaths have you had?
-why is it such a low cost?
-are all your needles and things sterile and new (for needles and things going into your rabbit)
-are you certified? (Seems obviously but yeah)

Also talk to your vet about the statistics and make sure she/he knows what he is talking about.

This also reinsures you about your worries hope I helped

He told me - "I have spayed many rabbits but most of them were about 6 month of age. Having a rabbit like yours (she is a big bunny, 3.5 yo) makes me nervous"
A little detail: his brother owns a vet clinic 2 minutes away from my house and I used to be coming there sometimes. Same thing - a good general practice vet (his brother), but without a detailed knowledge of rabbits, but still could be useful. Cost of spay there is about $200.
The suburb vet where cost is low said that it's just the way it is: fancy clinic for his brother and low-profile for him. I don't know why...
My concern is: the cost of good anesthesia can't be low...that makes me think that the meds they use would be something cheaper and not so good...

Yeah, maybe ask him what anetetuc

Sorry didn't mean to click reply

Ask him what he uses and where he gets it from (would of put the word that you have been using anest... But my autocorrect keeps changing it and I just have up ) )

Ring around the area and see if anyone has an reviews on him
