Welp, I'm a new cat owner (3 beautiful kittens), just under 5 months old
now, and we're looking to find a vet, get them spayed/neutered (as
applicable).

A little behind schedule, long story, but nonetheless, we'll make it
happen before they go into heat.

Long story short, what questions should I be asking of a vet before
setting up an appointment? What should I expect for a spay or neuter in
terms of price per cat?  I've heard of laser methods, thoughts?  Better
or worse then any other method?

For what it's worth, I'm in Calgary AB Canada, if anybody knows of a
good vet in the SW.
